An Exponent is : a number, letter, or algebraic expression written above and to the right of another number, letter, or expression called the base. In the expressions x 2 and xn, the number 2 and the letter n are the exponents respectively of the base x 2 exponent
The exponent indicates the power to which the base is to be raised. This means that if you have x 3 then you would multiply x by itself three times : x 3 = x x x or 33 = 3 3 3 Any number to zero power (40) equals 1.
Exponent Rules If two numbers having the same bases are being multiplied, add the exponents of those numbers. x 2 x 3 = x(2+3) = x 5 or 32 3 3 = 3(2+3) = 35 or 75 7 4 = 79
Exponent Rules If two numbers having the same bases are being divided, subtract the exponent of the 2 nd term from the 1 st term. x 3 ÷ x 2 = x(3 -2) = x 1 or 53 ÷ 5 2 = 5(3 -2) = 51 or 27 ÷ 2 3 = 24
Exponent Rules If an exponent is being raised by another exponent then multiply the exponents. (x 3)2 = x 3 = x 6 or (62)4 = 68
