Question

Create an equivalent expression for 18^−7 • 18^5.

Answer 1

18^ -2 = 1/8^2 = 1/324

When you multiply powers with the same base, add the exponent

18^ -7 • 18^5 18^ (-7+5) =18^ -2 =
1/18^2= 1/324

Answer 2

18^-2 = 1/18^2 = 1/324

Explanation:

When you multiply powers with the same base, add the exponents.

18^−7 • 18^5 = 18^(-7 + 5) = 18^-2 = 1/18^2 = 1/324
