Question

Use the rules of exponents to evaluate and simplify the following expression. bm)^-3

Answer 1

I'm assuming the expression is \[(bm)^{-3}\]
Whenever there is a negative exponent, you take away the negative and make the expression a reciprocal. Meaning you change bm to 1/bm. Therefore the simplified expression is \[\left( \frac{ 1 }{ bm } \right)^{3}\]
