WEBFeb 21, 2022 · Simplify so that the resulting equivalent expression contains no negative exponents. Solution. Raising y to the \(−3\) means we have to cube and invert, so \(y^{−3} = 1/y^3\). \[\dfrac{x^2}{y^{-3}} = \dfrac{x^2}{\tfrac{1}{y^3}} \nonumber \] To divide \(x^2\) by \(1/y^3\), we invert and multiply.
