Which is the correct simplified form of the expression

A.

Step-by-step explanation:

According to the laws of exponents, when exponents with the same base are divided, you keep the base and subtract the exponents:

Also according to the laws of exponents, when the exponent is negative, you put the base under '1' (turn it into a fraction) and make the exponent positive:

1/4 and 8/3 because:

the reciprocal if 4 is 1/4 because 4 is used as 4/1 and the opposite of that is 1/4. the opposite of 3/8 is 8/3 so that is the answer.

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.
