### What is the (a+b)^3 Formula?

Before we plunge into the depths of (a+b)^3, let’s establish a clear definition. The (a+b)^3 formula represents the third power or cube of a binomial expression, comprising two terms: ‘a’ and ‘b.’ In mathematical notation, it is represented as:

**(a+b)^3**

This seemingly enigmatic expression holds within it a world of mathematical possibilities, awaiting unraveling.

## Understanding the Basics

### Step 1: Cubing the Binomial

Our journey begins with the first crucial step in deciphering (a+b)^3. We must cube both terms enclosed within the parentheses. This process entails multiplying the binomial expression by itself twice, as depicted below:

**(a+b)^3 = (a+b)(a+b)(a+b)**

### Step 2: Expanding the Expression

To demystify this equation, we must expand it, employing the distributive property. This entails multiplying each term in the first expression by every term in the second and third expressions:

**(a+b)(a+b)(a+b) = a(a+b)(a+b) + b(a+b)(a+b)**

### Step 3: Applying the Distributive Property

Let’s delve even deeper by applying the distributive property to each term, unraveling the complexities within:

#### For the first term, let’s multiply ‘a’ by each term residing within the first set of parentheses:

**a(a+b)(a+b) = a(a^2 + ab) = a^3 + a^2b**

This detailed step elucidates how we calculate the first term within the expanded formula, shedding light on the intricacies involved.

#### Similarly, for the second term, we embark on a similar journey, multiplying ‘b’ by each term residing within the second set of parentheses:

**b(a+b)(a+b) = b(a^2 + ab) = ba^2 + b^2a**

This comprehensive breakdown offers insight into the second component of the expanded formula, providing clarity on its complexities.

### Step 4: Simplifying Further

The culmination of our efforts brings us to the point where we combine the results from the two expanded terms, resulting in the complete expression:

**(a+b)^3 = a^3 + 3a^2b + 3ab^2 + b^3**
