3 √8+3 √2

3√8 + 3√2 can be simplified by factoring out the common factor of 3 from both terms:

3(√8 + √2)

Then, we simplify the inside of the parenthesis by dividing the square roots by the greatest perfect square factor, which is 4 for √8 and 1 for √2:

3(2√2 + √2)

Finally, add the like terms to get the simplified expression:

3(3√2) = 9√2
