What is factoring and give the examples


Quick-Start Guide When you enter an expression into the calculator, the calculator will simplify the expression by expanding multiplication and combining like terms. At this point the calculator will attempt to factor the expression by dividing a G C F, and identifying a difference between two squares, or factorable trinomials. Use the following rules to enter expressions into the calculator. Variables Any lowercase letter may be used as a variable. Exponents Exponents are supported on variables using the ^ (caret) symbol. For example, to express x 2, enter x ^ 2. Note: exponents must be positive integers, no negatives, decimals, or variables. Exponents may not currently be placed on numbers, brackets, or parentheses. Parentheses and Brackets Parentheses ( ) and brackets [ ] may be used to group terms as in a standard expression. Multiplication, Addition, and Subtraction For addition and subtraction, use the standard + and - symbols respectively. For multiplication, use the * symbol. A * symbol is optional when multiplying a number by a variable. For instance: 2 * x can also be entered as 2x. Similarly, 2 * ( x + 5 ) can also be entered as 2 ( x + 5 ) ; 2 x * ( 5 ) can be entered as 2 x ( 5 ). The * is also optional when multiplying parentheses, example: ( x + 1 ) ( x - 1 ). Order of Operations The calculator follows the standard order of operations taught by most algebra books - Parentheses, Exponents, Multiplication and Division, Addition and Subtraction. The only exception is that division is not currently supported; attempts to use the / symbol will result in an error. Division, Square Root, Radi cals, Fractions Division, square root, radi cals, and fractions are not supported at this time. A future release will add this functionality.

that's all I can say basically I learned it this way.

Enter sin squared in Ti-83


The position of the exponent in trig functions is an anomaly in mathematical notation. While the square of sin x is commonly written as
sin^2(x) ,
the square of any other function is written as f(x) ^2 . For example, you wouldn't write ln^2(2) if you mean the square of the natural logarithm of 2, instead you write it as ln(2)^2 or (ln(2))^2 .
The calculator works the same way. To calculate the square of the sine of 3, for example, press
SIN 3 ) ^ 2 ENTER

I'm doing radicals I need to type an exponent into my calculator that goes before the square root not after. how do i do that (5) as an exponent square root of 32.....the answer is 2 but how do i type it...


Use the xth-root function to compute any root. It's the fifth entry on the MATH menu, which you can get by pressing the MATH key. The fourth entry on the same menu gives you the third root without needing the 3 to be specified.

For example, to compute the 5th root of 32, press 5 MATH 5 3 2 ENTER.

How do I find the square root of a number? and how do I enter scientific equations?


For square roots, use the square root key just to the left of the divide key. For example, 4 square-root = will give you 2.

The calculator doesn't have any way to store equations, scientific or otherwise. If you mean scientific notation, use the EE key just above the 7 key to enter exponents. For example, to enter 1.23x10^6, press 1 . 2 3 EE 6. For negative exponents, make sure to use the +- key to the right of the decimal point instead of the - key.

Exponents


To enter decimal exponents, use the x10^x key below the 3, followed by the exponent. For example, to enter one million, press 1 x x10^x 6 and see 1000000 (actually, the leading one is optional: if you press x10^x without a value, the calculator will supply a 1).

To raise a value to a number, use the x^ key above the sin, followed by the exponent. For example, to calculate 2^3, press 2 x^ 3 = and see 8.

Have a TI30Xa, i am trying to input 100 micro squared. how do I do this?


Usually you do not use the prefix micro by itself, it must be followed by the name of a unit: 1 micrometer=10^-6 meter. This being said, you want to enter 100*10^-6 and raise it to power 2.
For this you can use the exponent rules.
  1. 100*10^-6=(10^2)*(10^-6)=10^(2-6)=10^-4; product of powers =>algebraic sum pf exponents
  2. (10^-4)^2=10^(-4*2) =10^(-8) ; power of power =>product of exponents.
With your calculator: You have a key near which is written [10 to x]; you access the function with [2nd][10 to x]

In what follows, I will enter (10^-6)* 100 and square it. I will use the change sign (-) or [+/-] key
(-6) [2nd][10 to x] [*] 100 [=] [x^2] [=]

The first = calculates 100*10^(-6), the second [=] calculates the square of the number obtained after the first [=].
There are other ways that use parentheses to avoid ambiguities, but I think this is the safest one for you. Be warned that the result will most likely be displayed in scientific format, 1.00 -08 where the -08 will be raised with respect to the main level line. If not, the result will be 0.00000001

How to enter exponents


Hello,
You use the key on the 6th line of the picture. You enter the number, press the key then enter the exponent. At the end press =

If you want to extract roots other that square and cubic, you use the same key, but the exponent will be 1/4 , 1/5, 1/6.
Hope it helps.

How do i display exponents besides 2, or 3 on the sharp EL-531WH?


EL-531W SHARP:

If you want to find 5 to the power of 6 (5^6)
you hit the 5 button, then the button that says yx ( the x is in the exponent spot) then the 6 so it will looks like this 5^6 then press enter to get the answer...hope that helps!

Exponent Sign


To write 50 exponent in math mode, type your number then hit the key that has (x with the solid white exponent key). It's between the (x squared key) and the (log key) then you can enter the number 50 for your exponent. You can also hit the (x squared key) delete the 2 exponent and type in the exponent you want.
