Question

I need help for the working and answer to this question.

Answer 1

When multiplying the same bases with exponents, you add the exponents. When dividing you subtract the exponents.

Let's solve this problem from left to right.

`b^-^5 * b^3 / b^-^2`

Multiplication first:
`b^-^5 * b^3 = b^-^5^+^3 = b^-^2`

Division next:
`b^-^2 / b^-^2 = b^-^2^-^(^-^2^) = b^0 = 1`

because anything to the 0 power equals 1^.

Your answer is
`\boxed {1}`.
