Answer 2

$\bf \sqrt{18x^7}\qquad \begin{cases} 18\\ \qquad 2\cdot 3\cdot 3\\ \qquad 2\cdot 3^2\\ x^7\\ \qquad x^{2+2+2+1}\\ \qquad x^2\cdot x^2\cdot x^2\cdot x^1\\ \qquad (x^2)^3x^1\\ \qquad (x^3)^2x^1 \end{cases}\implies \sqrt{2\cdot 3^2\cdot (x^3)^2\cdot x} \\\\\\ 3\cdot x^3\sqrt{2\cdot x}\implies 3x^3\sqrt{2x}$
