The Solution:
Given:
We are required to find the equivalent of the given expression.
Simplifying the given expression, we get:
[tex]4x^2\sqrt{5x^4}\cdot3\sqrt{5x^8}=4x^2\times x^2\sqrt{5}\times3x^4\sqrt{5}[/tex][tex]=4x^2\times x^2\times3x^4\times\sqrt{5}\times\sqrt{5}=4x^4\times3x^4\times5=60x^8[/tex]
Therefore, the correct answer is [option B]
