Question

Write 1/64 as an expression with a negative exponent other than -1.

Answer 1

`8^(-2)`

Explanation:

Remember, if there is a negative within the power sign, you must put the power and base under 1:

8^-2 = 1/(8^2).

Simplify:

1/(8^2) = 1/(8 * 8) = 1/(64)

1/64 = 1/64, ∴
`8^(-2) = 1/64`
