Your problem statement is ambiguous. I'm going to assume you mean sqrt(5) * 2 * sqrt(3 + 7) because it's the only permutation of your problem statement that's worth simplifying. So,
sqrt(5) * 2 * sqrt(3 + 7) = sqrt(5) * 2 * sqrt(10) = sqrt(5) * 2 * sqrt(2) * sqrt(5) = 5 * 2 * sqrt(2) = 10 * sqrt(2)
All you need to do to earn an A in Algebra is follow instructions.
Case 1:
sqrt(5)[2(sqrt(3)+7]=
2sqrt(15)+7sqrt(5)
Case 2:
sqrt(5)[2sqrt(3)]+7=
2sqrt(15)+7
Case 3:
sqrt(5)[2sqrt(3+7)]=
2sqrt(50)=
10sqrt(2)
