Step-by-step explanation:

Negative power in the numerator becomes positive in the denominator

Option D, 3^7 * 1/(3^4)

Step-by-step explanation:

The equivalent is 3^7 * 1/(3^4) because if a power is negative, you can push it down stairs to make it positive.

 Option D, 3^7 * 1/(3^4)

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
