Question

can some one show me step by step of how to simplify the square root of 18

Answer 1

\[\sqrt{18} = \sqrt{9*2} = \sqrt{3*3*2} \]
as 9 is square of 3
then square root of 9 is 3
so \[\sqrt{18} = 3\sqrt{2}\]

Answer 2

i still dont get how u got yo anwser

Answer 3

\(\large \bf {
\sqrt{18}\qquad
\begin{cases}
18\to 3\cdot 3\cdot 2\\
18\to 3^2\cdot 2
\end{cases}\implies \sqrt{18}\implies \sqrt{3^2\cdot 2}
\\ \quad \\
\sqrt[{\color{brown}{ 2}}]{3^{\color{brown}{ 2}}}\cdot \sqrt[{\color{brown}{ 2}}]{2}\implies 3\cdot \sqrt[{\color{brown}{ 2}}]{2}\implies 3\sqrt{2}
}\)

see it now?
