Question

solve x^2=180

Answer 1

sqr both sides
x=+-sqr180
x=+-sqr(36*5)
x=+-6sqr5

Answer 2

\[x^ 2 = 180\]
\[x = \pm \sqrt{180}\]
\[x = \pm 6\sqrt{5}\]

Answer 3

\[\because x = \pm \sqrt{2\times2\times3\times3\times5}\]
i.e \[x = \sqrt{4 \times9\times5}\]
so \[x= 2\times3\sqrt{5}\]
\[x=6\sqrt{5}\]
