Question 69624
<pre>Simplify.     {{{7sqrt(700)}}}

I have come up with {{{70sqrt(7)}}}. Is this correct????

YES!

 I think that I have done something wrong, but I am not sure.

NO YOU DID NOTHING WRONG:

{{{7sqrt(700)}}} = {{{7sqrt(100*7)}}} = {{{7sqrt(100)*sqrt(7)}}} = {{{7*10sqrt(7)}}} = {{{70sqrt(7)}}}
