URGENT HELP PL
a and b are positive integers and a−b = 2. Evaluate the following: 27^(1/3)b/9^(1/2) a

I'm sorry, but I keep getting 3 for both a and b, so that equation wouldn't work.

Step-by-step explanation:

27^(1/3) is taking the cube root of 27, but you can plug that into a calculator to get 3.

9^(1/2) is taking the square root of 9, but you can also plug that into a calculator to get 3.

3 - 3 2

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

i think the answer is b
