Write the following cubes in expanded form:(i) `(2x+1)^3` (ii) `(2a-3b)^3` (iii) `[3/2x+1]^3` (iv) `[x-2/3y]^3`

Text Solution

AI Generated Solution

To expand the given cubes, we will use the following identities: 1. \( (a + b)^3 = a^3 + b^3 + 3ab(a + b) \) 2. \( (a - b)^3 = a^3 - b^3 - 3ab(a - b) \) Now, let's solve each part step by step. ### Part (i): Expand \( (2x + 1)^3 \) ...
