Answer: 
Step-by-step explanation:
If you took the nth root of x, it is the same as raising x to the power of 1/n. Therefore:
![\sqrt[7]{x^{2} } = (x^{2} )^{1/7} = (x^{\frac{2}{7}})\\\sqrt[5]{x^{3} } = (x^{3} )^{1/5} = (x^{\frac{3}{5}})](https://tex.z-dn.net/?f=%5Csqrt%5B7%5D%7Bx%5E%7B2%7D%20%7D%20%20%3D%20%28x%5E%7B2%7D%20%29%5E%7B1%2F7%7D%20%3D%20%28x%5E%7B%5Cfrac%7B2%7D%7B7%7D%7D%29%5C%5C%5Csqrt%5B5%5D%7Bx%5E%7B3%7D%20%7D%20%20%3D%20%28x%5E%7B3%7D%20%29%5E%7B1%2F5%7D%20%3D%20%28x%5E%7B%5Cfrac%7B3%7D%7B5%7D%7D%29)
And multiply:

(mn)3 = 3(mn) = 3 * m * n
so your answer is 3mn
Answer:
There seriously is not enough information.
Step-by-step explanation:
Answer:
x=32/7
Step-by-step explanation:
7x-2(1)=30 Plug in 1 as y and simplify.
7x-2=30 Add 2 on both sides of the equation.
<u>+2 +2</u>
7x=32 Divide both sides of the equation by 7.
<u>/7 /7</u>
x=32/7
Hope this helps...have an amazing day (。・∀・)ノ゙
