Simplify the Expression: 5^2 × 5^a × 5^3 Using Exponent Rules

To solve the expression $5^2 \times 5^a \times 5^3$, we will make use of the exponent rule for multiplication, which states that if you multiply powers with the same base, you add the exponents:

$a^m \times a^n = a^{m+n}$

Let's apply this rule step by step:

• Step 1: Identify the base of the power terms. In this problem, the base is $5$.
• Step 2: Write down all the exponents. The exponents we have are $2$, $a$, and $3$.
• Step 3: Add the exponents together:
  $2 + a + 3$.
• Step 4: Simplify the sum: $2 + a + 3 = 5 + a$.
• Step 5: Express the final result as a single power:
  The expression can be rewritten using the exponent rule as $5^{5+a}$.

Thus, the final simplified expression is $5^{5+a}$.
