If pm * p8= p16, and (p9)n =p-27, what is the value of m-n?

The first rule you have to know is

In other words, if you multiply two powers of the same base, you have to sum the exponents. So, we have

Which equals if and only if and thus .

The second rule you have to know is

In other words, to evaluate the power of a power, you have to multiply the exponents. So, we have

Which equals if and only if and thus .

Now that we found and , it's easy to conclude that

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.
