Question

Simplifying square roots problem below.

Answer 1

Break x⁴ into x³ and x¹, watch the step below

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

`= \sqrt[3]{ x^(3+1) }`

Remember that

`\sqrt{ x^(m+n) } = \sqrt{ x^(m) } \sqrt{ x^(n) }`

Use the property above to simplify the root

`= \sqrt[3]{ x^(3+1) }`

`=(\sqrt[3]{ x^(3) })( \sqrt[3]{x^(1)} )`
= x ∛x

The answer is first option
