Simplify the following:
sqrt(8) + 3 sqrt(2) + sqrt(32)
sqrt(8) = sqrt(2^3) = 2 sqrt(2):
2 sqrt(2) + 3 sqrt(2) + sqrt(32)
sqrt(32) = sqrt(2^5) = 2^2 sqrt(2):
2 sqrt(2) + 3 sqrt(2) + 2^2 sqrt(2)
2^2 = 4:
2 sqrt(2) + 3 sqrt(2) + 4 sqrt(2)
Add like terms. 2 sqrt(2) + 3 sqrt(2) + 4 sqrt(2) = 9 sqrt(2):
9 sqrt(2)
