Step-by-step explanation:
By Law of Indices,
8^(-2) = 8^0 / 8^2
= 1 / 64.
Start by multiplying b to both sides of the equation to get rid of the fraction. Now you have: Ub = ak.
To isolate a, divide both sides of the equation by k.
= a is the final answer.
Division and addition are the only operations involved.
