## anonymous 5 years ago the expression √ 72-3√ 2 written in simplest radical form is..?

1. anonymous

you have to break down whats under the radical so they match the other radical and pull the square out then subtract it out

2. anonymous

did that make sense?

3. anonymous

not really lol

4. anonymous

simplyy 72 by thing of it as 36*2 sqroot of 36 is 6 so sqroot of 72 is 3 sqroot2 6 sqrt2 - 3sqrt2 = 3sqrt2

5. anonymous

$\sqrt{72}=\sqrt{(36)(2)}=6\sqrt{2}$

6. anonymous
