Question

If x 7 0, what is the sum of 4
0
4+10 + 513387
in simplest form?

Answer 1

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

Explanation:

We have

`4 \sqrt[3]{ {x}^(10) } + 5x {}^(3) \sqrt[3]{8x}`

`4 \sqrt[3]{ {x}^(9) * x} + 5x {}^(3) √(8 * x)`

`4x {}^(3) \sqrt[3]{x} + 10 {x}^(3) \sqrt[3]{x}`

We can add these radicals since the radicand us equal.

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