Explanation:
3*sqrt(128) - 2sqrt(6)*4sqrt(3)
3*sqrt(128) = 3*sqrt(64*2) But the square root of 64 = 8
3sqrt(128) = 3*8 * sqrt(2) = 24 sqrt(2)
==================
2* sqr(6)*4sqrt(3) Combine the 2 and 4 = 8. Break apart the 6.
8* sqrt(3*2)*sqrt(3) Break apart the sqrt(3*2)
8*sqrt(3*2)*sqrt(3) = 8 * sqrt(3)*sqrt(2)*sqrt(3) but sqrt(3)*sqrt(3) = 3
8*sqrt(3)*sqrt(2)*sqrt(3) = 8*3*sqrt(2) = 24sqrt(2)
===================
24sqrt(2) - 24*sqrt(2)
