Answer 2

\[\sqrt{18x ^{5}}=\sqrt{9*2*x ^{4}*x}\]

Answer 3

\(\bf \sqrt{8x^5}-\sqrt{18x^5}\qquad {\color{blue}{ 18\implies 3\cdot 3\cdot 2\implies 3^2\cdot 2,\quad 8\implies 2\cdot 2\cdot 2\implies 2^2\cdot 2}}\qquad
\\ \quad \\
\sqrt{2^2\cdot 2x^5}-\sqrt{3^2\cdot 2x^5}\implies 2\sqrt{2x^5}-3\sqrt{2x^5}\implies ?\)

Answer 4

\[\sqrt{8x ^{5}}=\sqrt{4*2*x ^{4}*x}\]
