 LESSON 1: LAWS OF EXPONENTS HOMEWORK QUESTIONS PAGE 1

 

Review of Basic Exponent Laws:

 

Rule

Example

Explanation

am x an = am+n

32 x 35 = 37

Multiplication Rule - If the bases are the same, add the exponents

Division Rule - If the bases are the same, subtract the exponents

(am)n = amn

(32)3=36

Power Rule – When taking a power of a power, multiply the exponents

(ab)m = amam

(3 x 2)4 = 34 x 24

Power of a Product – Take each factor in the product to that power

Power of a Quotient – Take numerator and denominator to that power

 

Zero Exponents:     Rule:     a0 = 1           [Note that  00 is not defined]

 

Rational Exponents:
