You type in 5 (or any other number) and then use the carrot (exponent) button that looks like this: ^ and type in your exponent (5) and click the equal button

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.

Can you do the highest common factor on an fx-83GT PLUS casio calculator


The calculator has no application that will find the highest common divisor (or HCF) but that should not be difficult to do by hand.
Decompose the first number in prime factors. If a prime factor is repeated use the exponent notation: That helps
Decompose the second number in prime factors too, using the exponent notation.
Now look at the two decompositions. If a prime factor is present in both decomposition it must be in the HCD /HCF, with the smallest of the two exponents. Do that for all prime factors
Example;
(2^5)*3*(5^4)(7^3)*11
(2^3)*(5^6)*(11^2)*7
The prime factors that are present in both decompositions are
2, 5, 7, and 11
From the two decompositions select the smallest power of each
2^3, 5^4, 7, 11
The highest common divisor/Highest common factor is
(2^3)*(5^4)*7*11

How do I compute fractional exponents on the TI BA II Plus calculator?


The same way you raise a number to a non-fractional power, using the y^x button. For your example, press
3 y^x ( 1 / 1 2 ) =
or
3 y^x 1 2 1/x =

How do I find the fith root of a number


Use the general power key [Y^x], [X^y] or [^] with an exponent equal to 1/5. N-th root is equivalent to ()^(1/N)

HOW CAN I GET AN EXPONENT FROM TI-84 EX: B


You cannot use a letter as an exponent, unless you stored a numerical value in memory B (EX: 3 [STO>] [ALPHA] B stores value 3 in B)
For any numerical value of exponent ( positive, negative, integer, fraction, what have you) you use the general power key, marked with a caret [^] under the [CLEAR] key.

Example: To enter 15 to power 5
Type in 15
Press [^] key
Type in the value of the exponent (5) and press [ENTER]
You get 759375 as result.

TI-84 Plus Silver Edition. When dividing negative powers of ten by other negative powers of 10 the calculator it just adds the the negative powers together. How do i fix this? An example: 5*10^-10 /...


To enter an exponent, positive or negative, use the EE (Enter Exponent) key (the shifted function of the , key just above the 7 key). Do 5 2ND [EE] (-) 1 0 / 5 2ND [EE] (-) 1 0 ENTER and you'll see 1.

What I think you're doing (I can't be sure without seeing your keystrokes) is calculating
5*10^-10/5*10^-10 which is interpreted as (5*10^-10/5)*10^-10, which indeed is 10^-20.

Looking for a syntax


I am not sure what you are asking for?
Repeated multiplication (with same factor) is called raising a number (base) to a power. The exponent of the power is equal to the number of times the factor is repeated.
The calculator has several buttons to calculate powers.
For the square X*X you have a key [X^2].
For the cube X*X*X you MIGHT have a dedicated key [X^3].
However all calculators (scientific) have a universal power key marked [^] or [X^y] or [Y^x]

Example : In 5x5x5x5x5x5x5 you have a repeated multiplication, so the base is the factor (5) and the exponent is equal to 5. It is equal to the number of times the factor is repeated.
So 5x5x5x5x5x5x5 can be written much more efficiently as 5^7

Entering 5 then pressing the [^] key, followed by the exponent 7 gives the result 78125.
