Answer: second option.

Step-by-step explanation:

You need to descompose the radicand 8 and the radicand 50 into their prime factors:

8=2*2*2=2^2*2\\50=2*5*5=2*5^2

Then you can rewrite the expression:

\sqrt{8}+\sqrt{50}

=\sqrt{2^2*2}+\sqrt{2*5^2}

Since:

\sqrt{a^2}=a

You can simplify the expression:

=2\sqrt{2}+5\sqrt{2}

As the indices and the radicands are the same, you can make the addition:

=7\sqrt{2}
