Understanding the Problem

When dealing with exponents, it's essential to understand the rules that govern their behavior. In this case, we're given the expression $y^3 \cdot y^3$, and we're asked to simplify it. To start, let's recall the rule for multiplying variables with exponents: when we multiply two variables with the same base, we add their exponents.

Applying the Rule for Multiplying Variables with Exponents

The given expression $y^3 \cdot y^3$ can be simplified by applying the rule for multiplying variables with exponents. Since both terms have the same base ($y$) and the same exponent ($3$), we can add their exponents.

Simplifying the Expression

To simplify the expression, we add the exponents of the two variables:

$$y^3 \cdot y^3 = y^{3+3} = y^6$$

This means that the simplified form of the expression $y^3 \cdot y^3$ is $y^6$.

Understanding the Concept of Exponents

Exponents are a shorthand way of representing repeated multiplication. In the expression $y^3$, the exponent $3$ indicates that the variable $y$ is multiplied by itself three times. For example, $y^3$ can be written as $y \cdot y \cdot y$.

Applying the Concept of Exponents to the Given Expression

In the given expression $y^3 \cdot y^3$, we can apply the concept of exponents to simplify it. Since both terms have the same base ($y$) and the same exponent ($3$), we can add their exponents.

Simplifying the Expression Using the Concept of Exponents

To simplify the expression, we add the exponents of the two variables:

$$y^3 \cdot y^3 = y^{3+3} = y^6$$

This means that the simplified form of the expression $y^3 \cdot y^3$ is $y^6$.

Real-World Applications of Exponents

Exponents have numerous real-world applications, including:
