Answer 5

oh, this site loves me. (disconnected)
\(\large\color{black}{ \displaystyle \sqrt{864} }\)

the sum of digits is
\(\large\color{black}{ \displaystyle 8+6+4=18 }\)
(so if sum of digits is divisible by 9, the number also is divisible by 9.

and it is an even number, so you can take 18 out.

\(\large\color{black}{ \displaystyle 864 \div 18 =48 }\)
So,
\(\large\color{black}{ \displaystyle \sqrt{864} \div \sqrt{18} =\sqrt{48} }\)

Answer 6

and 48 is 16 times 3.

Answer 7

So this is how you can brake it down.

\(\large\color{black}{ \displaystyle \sqrt{864} = \sqrt{18} \times \sqrt{48} }\)

\(\large\color{black}{ \displaystyle \sqrt{864} = \sqrt{18} \times \sqrt{16}\times \sqrt{3} }\)

\(\large\color{black}{ \displaystyle \sqrt{864} = \sqrt{9} \times \sqrt{2}\times \sqrt{16}\times \sqrt{3} }\)
