Think of it as (24x)^1/2 then use chain rule. Which means first derive (24x)^1/2 as deriving u^1/2 (substitute u for 24x), then deriving 24x, finally write those 2 derivatives as a multiplication (as in a*b).
The answer is D.
There is 1 desired outcome (4) and 6 possibilities.
1/6
1/6 = .16
Hope this helps!
5.23 because 523 divided by 100 will bring you to the solution of 5.23.
