anonymous 5 years ago what is the cube root of 56x to the fifth power times y.

1. anonymous

$\sqrt[3]{56}=\sqrt[3]{8\times 7}=\sqrt[3]{8}\times \sqrt[3]{7}=2\sqrt[3]{7}$ is as start

2. anonymous

also $\sqrt[3]{x^5}=\sqrt[3]{x^3x^2}=x\sqrt[3]{x^2}$

3. anonymous

so a two comes out, an x comes out, and there is some stuff left in. final answer is $2x\sqrt[3]{x^2y}$

you did cube root of 56 but where is to the fifth power times y? :(
