hi
Customer Service Rep Says:9/9 11:48
this is a expression with whole cube
Customer Service Rep Says:9/9 11:52
So here we will use this property (a + b)^3 = a^3 + b^3 +3ab^2 + 3a^2*b
Customer Service Rep Says:9/9 11:53
So in this question a = 1 and b = h so we will expand it with the help of above given expression
Customer Service Rep Says:9/9 11:53
=> (1 + h)^3 = 1 + h^3 + 3h^2 + 3h
Customer Service Rep Says:9/9 11:54
'Winpossible' left chat session.
