$\left(7x^{\frac{2}{3}}\left(xy^{-121}\right)^{\frac{1}{2}}\right)^4$

Learn how to solve power of a product problems step by step online. Solve the product power (7x^(2/3)*(xy^(121*-))^(1/2))^4. Multiply 121 times -1. Divide 2 by 3. Divide 1 by 2. The power of a product is equal to the product of it's factors raised to the same power.
