+1090 How do I simplify: $${\sqrt{{{\mathtt{25}}}^{{\mathtt{2}}}{\mathtt{\,\small\textbf+\,}}{{\mathtt{4}}}^{{\mathtt{2}}}}}$$
I know the answer's $${\sqrt{{\mathtt{641}}}}$$, but how do I get to it?
+1090 I'm still getting the hang of square roots multiplying, adding, etc...
+1090 How do I multiply (say the question was: $${\sqrt{{{\mathtt{25}}}^{{\mathtt{2}}}{\mathtt{\,\times\,}}{{\mathtt{4}}}^{{\mathtt{2}}}}}$$)
