Question

Rewrite the following without an exponent.
(−4)^−2

Answer 1

`\bf a^{-{ n}} \implies \cfrac{1}{a^( n)}\qquad \qquad \cfrac{1}{a^( n)}\implies a^{-{ n}} \\ \quad \\ % negative exponential denominator a^{{ n}} \implies \cfrac{1}{a^(- n)} \qquad \qquad \cfrac{1}{a^(- n)}\implies \cfrac{1}{(1)/(a^( n))}\implies a^{{ n}} \\\\ -------------------------------\\\\ (-4)^(-2)\implies \cfrac{1}{(-4)^2}\implies \cfrac{1}{(-4)(-4)}\implies \cfrac{1}{16}`
