Factors A number that divides a number with zero left over
Order of operations PEMDAS
Exponent the number above a number telling how many times a number is to be multiplied by itself
Base The repeated factor of a number in exponential form
Power The exponent
(-3)^2 is also known as (-3) x (-3)
-3^2 is also known as -3 x -3
Prime number Number that has no factors
Composite Number Has factors
GCF Greatest Common Factor
x^2 x y^5, xy^3 (x) x (y^3)
prime factorization 120 (2^3),( 3), (5)
Prime Factorization of 78 and 124 Find factors of both^ and take what is in common and multiply it
12, x^2, y^5/8, x^4, y^2= 3, 7^3/2, x^2
Rational Number A number that can be put into a fraction
Rational number 5, 5/1 1/5
Negative Rational Numbers if number is -7 and is put 1/-7 move the negative to the top
4x^3 y^5 * 3x^2 y z^2= 12 x^12 y^5
(x^3y^5)^4= x^12 y^20 multiply exponent out of perenthesis and the one from inside the perenthesis
x^0= x (number of base)
(x)^-3 (-x) x (-x) x (-x) multiply ex but negative
x^-3, y^2/a^2, b^-3 y^2, b^3/ a^2, x^3 (negatives move to opposite side of the division bar
x^3, y^2/ a^2, b^3 x^3, y^2, a^-2, b^-3 if the numbers move from bottom to top the exponents become negative
x^-3, y^2 z^0/ X^-2, y^-3 = x^2, y^5/x^3
