Question

Which expression is equivalent to 3sq 256x^10 y^7

Answer 1

Answer: Correct answer is b on the test

Explanation:

Answer 2

For this case we have the following expression:

`\sqrt[3]{256x^(10)*y^(7)}`

We can rewrite it in the following way:

`\sqrt[3]{(64*4)x^(9+1)*y^(6)*y^(1)}`

Simplifying, taking into account that:
`ax ^ b * ax ^ b = (a * a) x^(b+b)`, we have the following:

`4x^3*y^2(\sqrt[3]{4x*y} )`

Thus, the simplified expression is given by:

`4x^3*y^2(\sqrt[3]{4x*y} )`

Answer:

`4x^3*y^2(\sqrt[3]{4x*y} )`
