Answer:

Last choice
10x^4√(6)+x^3√(30x)-10x^4√(3)-x^3√(15x) is correct.

Explanation:


\left(√(10x^4)-x√(5x^2)\right)\left(2√(15x^4)+√(3x^3)\right)


\left(x^2√(10)-x\cdot x√(5)\right)\left(2\cdot x^2√(15)+x√(3x)\right)


\left(x^2√(10)-x^2√(5)\right)\left(2x^2√(15)+x√(3x)\right)


x^2√(10)\left(2x^2√(15)+x√(3x)\right)-x^2√(5)\left(2x^2√(15)+x√(3x)\right)


2x^4√(150)+x^3√(30x)-2√(75)x^4-x^3√(15x)


2x^4\cdot5√(6)+x^3√(30x)-2\cdot5√(3)x^4-x^3√(15x)


10x^4√(6)+x^3√(30x)-10√(3)x^4-x^3√(15x)


10x^4√(6)+x^3√(30x)-10x^4√(3)-x^3√(15x)

Hence final answer is
10x^4√(6)+x^3√(30x)-10x^4√(3)-x^3√(15x)
