Given that a^b = x, evaluate the following: a^b+2--->(the 2 is added to the b in the exponent so the 2 is also an added exponent next to the b)

x* a^2

Step-by-step explanation:

a^b = x

Remember that when we add exponents, we multiply the bases

x^2 * x*4 = x^(2+4)

We want a^ (b+2) so that means a^b * a^2

We need to multiply both side by a^2

a^b * a^2 = x * a^2

a^ (b+2) = x* a^2

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.
