Simplify the Expression: 7^(x+a) × 7^a × 7^x

Question

Reduce the following equation:

$7^{x+a}\times7^a\times7^x=$

00:00 Simplify the following problem

00:04 According to the laws of exponents, the multiplication of exponents with equal bases (A)

00:08 equals the same base raised to the sum of the exponents (N+M)

00:13 We will apply this formula to our exercise

00:17 We'll maintain the base and add the exponents together

00:44 Let's group the factors together

00:47 This is the solution

$7^{2x+2a}$
