Multiply Powers: Solving 7^9 × 7^1 Using Exponent Rules

$7^9\times7^1=$

To solve the expression $7^9 \times 7^1$, we need to apply the rules of exponents, specifically the multiplication of powers rule. According to this rule, when we multiply two powers with the same base, we keep the base and add the exponents together.

• The expression can be written as $a^m \times a^n = a^{m+n}$, where $a$ is the base and $m$ and $n$ are the exponents.
• In this case, our base $a$ is 7, and our exponents are 9 and 1.
• Applying the formula, we have: $7^9 \times 7^1 = 7^{9+1}$.
• Simplifying the exponent: $9 + 1 = 10$.

Thus, the expression simplifies to: $7^{10}$.
