Question

evaluate the following expressions

4^-1

6^-2

Answer 1

To evaluate these expressions, we need to use the rule of exponentiation that states "a raised to the power of -n is equal to 1 divided by a raised to the power of n."

1. 4^-1 = 1 / 4^1 = 1 / 4 = 0.25

2. 6^-2 = 1 / 6^2 = 1 / 36 = 0.0278 (rounded to four decimal places)
