Question

40 points need NOW Simplify the expression.

Answer 1

`7xy^(2) \sqrt[3]{2xy}`

Explanation:

`\sqrt[3]{686x^(4) y^(7)}`

`686 = 343 * 2`

`x^(4) = x^(3) * x`

`y^(7) = y^(3) * y^(3) * y`

`\sqrt[3]{343} =7`

`\sqrt[3]{x^(3)} = x`

`\sqrt[3]{y^(3)* y^(3)}` =
`y^(2)`

so you're left with 2, x, and y inside the cube root, and 7, x, and y^2 outside

`7xy^(2) \sqrt[3]{2xy}`
