Simplify the Expression: 8^4 × 8 × 8^-1 Using Exponent Laws

Question

Insert the corresponding expression:

$8^4\times8\times8^{-1}=$

00:00 Simply

00:03 Any number to the power of 1 is always equal to itself

00:07 We'll use this formula in our exercise, and raise to the power of 1

00:11 According to the laws of exponents, multiplication of powers with equal base (A)

00:15 equals the same base to the power of the sum of exponents (N+M)

00:19 We'll use this formula in our exercise

00:28 Note that we are adding a negative factor

00:34 Positive times negative is always negative, therefore we subtract

00:40 And this is the solution to the question

$8^{4+1-1}$
