Simplify the Expression: Converting 1/(20²) to Its Final Form

Question

Insert the corresponding expression:

$\frac{1}{20^2}=$

00:00 Simplify the following problem

00:03 According to the exponent laws, a number raised to the power of (-N)

00:06 equals the reciprocal number raised to the opposite power (N)

00:10 We'll apply this formula to our exercise

00:13 We'll convert to the reciprocal number, and raise it to the opposite power (times(-1))

00:17 This is the solution

$20^{-2}$
