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

Question

Insert the corresponding expression:

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

00:00 Simply

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

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

00:10 We'll use this formula in our exercise

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

00:17 And this is the solution to the question

$20^{-2}$
