Answer:
Vales of a =3 and b = 6
Step-by-step explanation:
Given that:
.....[1] where a and b are positive integers
we can write 81 and 24 as;


We have [1] as;

Using power rules;

which implies a = b
then;


On comparing both sides we have;
a = 3 and

⇒
Therefore, the value of a and b are, 3 and 6
Answer:

Step-by-step explanation:
Given the function: 
f(x) =number of days it would take to complete the project
x =number of full-time workers.

The domain of a function is the complete set of possible values of the independent variable.
In this case, the independent variable is x, the number of full-time workers. We have shown that x cannot be zero as there must be at least a worker on ground.
Therefore, an appropriate domain of the function f(x) is the set of positive integers (from 1 to infinity).

15% of 40...
15% in decimal form is 0.15...
0.15(40)= 6
your answer is 6.
