Radical and Fractional exponents

Unit 3: Radicals

By Crissy Matlick

Match

Match the following exponent rules:

• Product Rule: $$x^a\cdot x^b=$$

• Power Rule:

  $$\left(x^a\right)^b=$$

• Quotient Rule:

  $$\frac{x^a}{x^b}=$$

• Negative exponent rule

  $$x^{-a}=$$

• Zero exponent rule:

  $$x^0=$$

• $$x^{\left(a+b\right)}$$

• $$x^{ab}$$

• $$x^{\left(a-b\right)}$$

• $$\frac{1}{a}$$

• $$1$$
