Hello
To raise a number to an arbitrary power you use the [^] key below [CLEAR]

7.5 to power 4 is entered as follows
7.5 [^]4 [ENTER] gives 3164.0625

Other exemples (if you are interested)
Fifth root of 300 is enterd as 300[^](1/5) [ENTER]
If you raise a number to a negative power use the small minus sign (-)

157 to power of -3
157 [^][(-)]3 [ENTER] gives 2.584E-7 =2.584x10^(-7).

Hope it helps

SOURCE: How do I add Exponents on my T1-30xa calculater

Hello,
There is a rule of Algebra, that says
(a^m)[x] (a^n) = a^(m+n)

a is the base of the power, n, and m are the exponents. As you can see, multiplying two powers of the same base is equal to the power of the (common) base with the sum of the exponents.
If that is what you had in mind, the calculator uses the rule correctly and no intervention from you is necessary.
If you enter (2^4)[x](2^6), the calculator will give 1024, which is 2^10.

I may be wrong, but what you call add exponents refers really to performing addition where addends (the terms you add) are arbitrary powers, such as
2^7 + (5.5^3) - (1/3)^4

Once you enter a power term, the calculator calculates it and the result is now just a number. It can be added, subtracted, multiplied

For the exemple above
2 [Y to the x] 7 + (5.5)[Y to the x] 3 -(1/3) [Y to the x] 4 [=] yields 294.3626543

For the cube of 5.5 you can use the key combination [2nd][X^3]

Hope it helps.

2negative 3 plus 3negative 3


Just want to make sure that we are on the same page.

2^(-3) + 3^(-3)

2 to the exponent -3 + 3 to the exponent -3

Because of BEDMAS, we have to do the exponent calculations first and then do the addition between the two terms last.

The rule of negative exponents is you put 1 over the base to the same exponent, but change the exponent from negative to positive.

=1/(2^3) + 1/(3^3)

= 1/8 + 1/27

To add or subtract numbers, we need a common denominator.

Let's factor 8 and 27 to get the lowest common multiple.

8 - 1 2 4 8
27 - 1 3 9 27

Nothing in common to eliminate, so we have to use 8 x 27 or 216.

27/216 + 8/216 = 35/216

Good luck,

Paul

How do i get a negative exponent?


I don't have this calculator, but let's give this a shot and see if it gives us the correct answer.

Let's try 10 to the exponent -2. The rule for negative exponents is to put 1 on the top and the term with a positive exponent on the bottom. In this case, it would be 1 on the top and 10 to the exponent 2 on the bottom, or 1 / 100 or 0.01.

In the calculator, enter 10, hit the x to the power of y key, left bracket (, the negative key (-), 2, the right bracket ), and finally the = key. You might not have to enter the left and right brackets, but I like to enter them to understand what I enter in brackets is the exponent.

Let me know if it works and if you have any other questions.

Good luck.

Paul

Where is the exponent key on the 531x


If you mean the key to raise a number to an exponent, it's the key marked "y^x", two keys above the "7" key. If you mean the key to enter an exponent of ten, it's the key marked "Exp", just above the "7" key.

I don't know what buttons to hit to put exponents into my TI-68


For an exponent of ten, use the EE (Enter Exponent) key located just above the 7 key.

How do you put in the number in scientific notation on the TI 34 II calculator?


Type in the mantissa, then the EE key (for Enter Exponent) above the 7 key, then the exponent. If it's a negative exponent, press the (-) key to the right of the decimal point before entering the exponent.

What does the ee symbol above the qoutation mark mean


Hello,
What you call a quotation mark is in fact a comma. It is used to separate arguments inside commands that require more than one arguments, or the elements of a list.
The [EE] that you access by pressing [2nd][comma] is very useful in scientific areas of studies such as physics and chemistry. It is a shortcut for times 10 to a power.
If you want to enter Avogadro's number you enter
6.02[2nd][EE]23 [ENTER]
The electon charge is
1.6[2nd][EE] (-)19 [ENTER] . Here the (-) is the change sign key located between [.] and [ENTER]

The [2nd][EE] sequence must always be followed by an exponent even if exponent is 0.
Try these
[2nd][EE] 0 [ENTER] (Surprised? You should'nt be!)
[2nd][EE] 1 [ENTER]
[2nd][EE] (-) 3 [ENTER]

Hope it helps.

How do I calculate compound interest? I want to calculat 3500 (1 +.064) to the exponent 3.5 to get 4348.74. How do I perform this on my TI-30XA? Thanks.


Hello,
You enter that as follows
3500[x] (1.064)[Y to the x]3.5 [=] . Note that [x] is the multiplication sign.
Hope it helps.
