Find : `(a +b) (a + b) (a + b)`

Answer

To find the product of \((a + b)(a + b)(a + b)\), we can follow these steps:

### Step 1: Rewrite the expression
We can rewrite the expression as:
\[ (a + b)^3 \]

### Step 2: Use the Binomial Theorem
According to the Binomial Theorem, we know that:
\[ (a + b)^3 = a^3 + 3a^2b + 3ab^2 + b^3 \]

### Step 3: Expand using the formula
Now, we can expand \((a + b)^3\) using the formula:
\[ (a + b)^3 = a^3 + 3a^2b + 3ab^2 + b^3 \]

### Step 4: Write the final expression
Thus, the final expression for \((a + b)(a + b)(a + b)\) is:
\[ a^3 + 3a^2b + 3ab^2 + b^3 \]

### Summary of the solution
The product of \((a + b)(a + b)(a + b)\) is:
\[ a^3 + 3a^2b + 3ab^2 + b^3 \]
