Question

Evaluate f^-2g for f = 3 and g = 27.
a) 1/3
b) 3
c) 9

Answer 1

\[f ^{-2}g = ?\]

We've looked at negative exponents in two other problems. Can you tell me how this would simplify?

Answer 2

b

Answer 3

If it is a negative exponent then that means it goes in the denominator and is raised to the power so if f = 3 then:
\[f^{-2} = 1/(f^{2})\] = 1/9

if g = 27 then
27/9 = 3
