## Tinascott one year ago (m^-1m^5 / m^-2)^-3 What is the simplified form of the expression?

well I'd apply the index laws inside the brackets 1st. and start with the numerator of the fraction. for multiplication, add the power $x^a \times x^b = x^{a \times b}$ next you'll need the law for division, subtract the powers $\frac{x^a}{x^b} = x^{a - b}$ then looking at the power of a power, multiply the powers $(x^a)^b = x^{a \times b}$ I hope this helps you get the solution.

its not a pretty question.... just asks you to use some laws...
