Question

0
4+10 + 513387
in simplest form?

Answer 1

Answer:

$14 {x}^{3} \sqrt[3]{x}$

Step-by-step explanation:

We have

$4 \sqrt[3]{ {x}^{10} } + 5x {}^{3} \sqrt[3]{8x}$

$4 \sqrt[3]{ {x}^{9} \times x} + 5x {}^{3} \sqrt{8 \times x}$

$4x {}^{3} \sqrt[3]{x} + 10 {x}^{3} \sqrt[3]{x}$

We can add these radicals since the radicand us equal.

$14 {x}^{3} \sqrt[3]{x}$
