Re: If, for all x and y, x # y = x*y^2, which of the following is equal to [#permalink]

x # y = x*\(y^2\)

To find 3 # 4 we need to compare what is before and after # in 3 # 4 and x # y
=> We need to replace x with 3 and y with 4 in 12 in x # y = x*\(y^2\) to get the value of 3 # 4

=> 3 # 4 = 3 * \(4^2\) = 3 * 16 = 48 = 12 * 4 = 12 * \(2^2\) = 12 # 2

So, Answer will be E
Hope it helps!
