Answer 2

solve it part by part, meaning multiply the rational part together then resolve the square root portion.

3 sqrt(2) * 5 Sqrt(2)
= 15 sqrt(2) * sqrt(2)
= 15* 2
=30

Answer 3

if it is added?

Answer 4

if it is 3sqrt(2) + 5 sqrt(2)

Let us take sqrt(2) as x.

so it will be 3 x + 5x = 7x.

the final answer would be 7 sqrt(2). So for addition you can just take sqrt(2) as the common term and factorise accordingly.
