Answer 1

Answer:

B

Step-by-step explanation:

Answer 2

The equivalent expression is $16x^{8}$. So, the correct option is B.

Given:

The given expression is:

$4x^2\sqrt{5x^4}3\sqrt{5x^8},x\neq 0$

To find:

The equivalent expression.

Explanation:

We have,

$4x^2\sqrt{5x^4}3\sqrt{5x^8}$

On simplification, we get

$=4x^2(x^2\sqrt{5})3(x^4\sqrt{5})$

$=(4\times 3)(x^{2+2+4})(\sqrt{5}\times \sqrt{5})$

$=12(x^{8})(5)$

$=16x^{8}$

Therefore, the correct option is B.
