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?

25^2=625

4^2=16

625+16=641

So what's the problem?

Notice that...... √(25² * 4²) = √[(25 * 4)² ] = √ [(100)² ] = 100
