Answer:

a = 3 and b = 6

Explanation:

(arᵇ)⁴ = 81 r²⁴

We are ask to find a and b

In the above equation, lets open up the bracket. Then it becomes;

a⁴ r⁴ᵇ = 81 r²⁴

Comparing the left and right-hand side of the equation;

a⁴ = 81

a⁴ = 3⁴

a = 3

Also, r⁴ᵇ = r²⁴

4b = 24

Divide both-side of the equation by 4 to get the value of b

4b/4 = 24/4

(On the left-hand side of the equation 4 on the numerator will cancel-out 4 at the denominator while on the right hand-side of the equation 24 will be divided by 4)

b = 6
