The answer is 15√3, or 25.981.
Here's the math:
original problem was 3√48 + √27
= 3(√16)(√3) + (√9)(√3)
= (3x4)(√3) + (3)√3
= (12)√3 + 3√3
= 12√3 + 3√3
= 15√3

Since neither of these is a perfect square, I suggest a calculator. The sqrt of 48 will be slightly short of 7, and that of 27 slightly more than 5. So if your answer is very different from 26, something is wrong.

3*sqrt(48) + sqrt(27)
= 3*sqrt(2*2*2*2*3) + sqrt(3*3*3)
= 3*2*2*sqrt(3) + 3*sqrt(3)
= 12*sqrt(3) + 3*sqrt(3)
= 15*sqrt(3)
