How can we simplify various expressions using exponents?
The following are ways to solve simple mathematical expressions with the same base:
To multiply two numbers with different exponents, add the exponents:
(x2)(x4) = (xx)(xxxx) = xxxxxx = x2+4 = x6
To raise a number with a power, multiply the exponents:
(x3)3 = (x3)(x3)(x3) = (xxx)(xxx)(xxx) = xxxxxxxxx = x(3x3) = x9
