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

Question

Reduce the following equation:

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

00:00 Simply

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

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

00:13 We will use this formula in our exercise

00:17 We'll keep the base and sum the exponents

00:44 Let's group the factors

00:47 And this is the solution to the question

$7^{2x+2a}$
