what is the square root 45?
The square root of 45 can also be simplified using surds.
root 45 = root 9 times root 5
so 3 times root 5

Hi Zacismyname
When you make a post there is a btton in the ribbon called [Math Formula]
if you open that and type in 3*sqrt(5) this will be your output. $${\mathtt{3}}{\mathtt{\,\times\,}}{\sqrt{{\mathtt{5}}}}$$
Thanks :)
