In the case of (xy)^3 the numbers on pascals triangle are 1 3 3 1 Which means the answer is 1*x^3 3*(x^2)(y) 3*(x)(y^2) 1*y^3 Do you see a pattern with x and y The numbers in pascals triangle represents how many different combinations can be taken from a limited number of something (Ex Each y term power will increase over the terms, like, 1 which represents NIL in this process, y, then y 2, then y 3 Example (xy) 4 Since the power (n) = 4, we should have a look at the fifth (n1) th row of the Pascal triangleQuestion Identify the binomial expansion of (xy)^3 Answer by rapaljer (4671) ( Show Source ) You can put this solution on YOUR website!
