I am needing to find out what key I can push for an exponent. I have an exponent that is 2520 and I dont know what button to push for it.

The problem is as follows:

3000 ( 1+ 0.06/360) exp.2520

3000 ( 1.000166667) exp. 2520

3000 - 4565.72

1565.72

Now how in the world did they get 4565.72. What buttons am I needing to push.

### How do I express 5765 in exponential form?

Hello there,
First you need to find the P'rime factors' of 5765 which are 5 * 1153
Therefore the Exponential form of 5765 is 51 x 11531
You MUST find the PRIME FACTORS
(That means the two Prime numbers that when multiplied together gives the answer.

### Demonstrate how to multiply two binomials

Try to seek these: By using the suggested format:
Suggested su
• 1

Arrange each term in each binomial in order of degree from greatest to least. The degree of a binomial is the exponent attached to the term. For example, 4x^2 is a second degree term.

• 2

Multiply each term in the binomial that is being subtracted by -1 to turn it into an addition problem. For example, the problem (8x^2 + 8) - (x^2 - 2) becomes (8x^2 + 8) + (-x^2 + 2).

• 3

Combine like terms. In the example problem, the x^2 terms are combined and the constant terms are combined, yielding (8x^2 + 8) + (-x^2 + 2) = 7x^2 + 10.

Multiplying Binomials
• 4

Understand the F.O.I.L. method. F.O.I.L. is an acronym standing for first, outside, inside and last. It means that you multiply the first number of the first binomial by the first number of the second, then the numbers on the outside (the first term of the first binomial by the second term of the second binomial) and so on. This ensures that both numbers in the first binomial are multiplied by both numbers in the second.

• 5

Use the F.O.I.L. method to multiply the two binomials together. For example, (3x + 4)(3x - 4) = 9x^2 +12x - 12x - 16. Notice that -12x is the product of the outside terms and -16 is the product of the last terms, 4 and -4.

• 6

Simplify. There will almost always be like terms to combine. In the example, 12x and -12x cancel out, yielding the answer 9x^2 - 16.

Dividing Binomials
• 7

Use the distributive property to divide both terms in the binomial by the monomial divisor. For example, (18x^3 + 9x^2) / 3x = (18x^3 / 3x) + (9x^2 / 3x).

• 8

Understand how to divide by a term. If you are dividing a higher order term by a lower order term, you subtract the exponent. For example, y^3/y = y^2. The number part of each term is handled like any other division problem. For example, 20z / 4 = 5z.

• 9

Divide each term in the binomial by the divisor; (18x^3 / 3x) + (9x^2 / 3x) = 6x^2 + 3x.

### What is a prime number

a prime number is a number that can only be multiplied by itself and 1 - example 3 can only be multiplied by itself and 1.

### How to use the exp key

I think it is case of mistaken identity. There is a function called the power function. The general form of it is a*(b)^x or a times (b) to the power of x. a is just a constant factor (not equal to 0) and b is the so-called base ( also different from zero). Personnally I call this function the power function, but you find it is often called the exponential function.
The exponential function e^x is similar to the power function. The main difference is that its base is a certain irrational number called e (=2.718281828...).
What you want to do, as far as I can guess is to calculate 2000*(1+0.12)^20.
Simplify your life and set 1+0.12 as 1.12, and type in 2000 [*]1.12^20=
1.12^20=9.646293093. Multiplied by 2000, this gives you a final result 19 292.58
To enter the the power use the key marked as [X^y], [Y^x] or [^]

### How to fix err over flow massage when calculating e^?

The function grows very fast and your calculator cannot handle number larger than 10^100. This puts a limit on the argument of the exponential.
e^230 is about 7*10^99 and e^231 overflows the memory.
Now, that you know the calculator limitations keep the exponent less than 231 and you will not have the error message. Of course, if you multiply e^230 by a number larger than 1 you will exceed the limit.
Also, to get the exponential, you press [2nd][LN] and you do not press the caret key [^].

### 5000e to the (0.08)power time (2)

On this calculator the exponential function requires the argument be entered first. To calculate the exponential of a number, you enter the exponent (0.08) then press [2nd][LN].
For your calculation, you should calculate e^(0.08) then multiply the result by (5000x2=10000). The result should be 10 832.87068

### The screen have a E. What do that mean?

If the screen has only an "E" on it, an error has occurred.

More likely, you are seeing something like:
1.2753E12

If this is the case, the "E" is short for "Exponential" and is a method of saying "The number is too big for me to show, but here is the closest I can tell you". To translate that into a number, take the number AFTER the E as an exponent of 10, then multiply that by the numbers before the E. In other words, write the number before the E, then move the decimal point to the right by the number of places after the E.

In the example above, the number it is displaying is:
1,275,300,000,000

### Convert 4 2/9 to a decimal

Step 1: Find a number you can multiply by the bottom of the fraction to make it 10, or 100, or 1000, or any 1 followed by 0s. Step 2: Multiply both top and bottom by that number. Step 3. Then write down just the top number, putting the decimal place in the correct spot (one space from the right for every zero in the bottom number) Example 1: Express 3/4 as a Decimal Step 1: We can mulitply 4 by 25 to become 100
Step 2: Multiply top and bottom by 25:
×25 3 = 75

4 100 ×25 Step 3: Write down 75 with the decimal place 2 spaces from the right (because 100 has 2 zeros);

Example 2: Express 3/16 as a Decimal Step 1: We have to mulitply 16 by 625 to become 10,000
Step 2: Multiply top and bottom by 625:
×625 3 = 1,875

16 10,000 ×625 Step 3: Write down 1875 with the decimal place 4 spaces from the right (because 10,000 has 4 zeros);

Example 2: Express 1/3 as a Decimal Step 1: There is no way to multiply 3 to become 10 or 100 or any power of 10, but we can calculate an approximate decimal by choosing to multiply by, say, 333
Step 2: Multiply top and bottom by 333:
×333 1 = 333

3 999 ×333 Step 3: Now, 999 is nearly 1,000, so let us write down 333 with the decimal place 3 spaces from the right (because 1,000 has 3 zeros):
Answer = 0.333 (accurate to only 3 decimal places !
