Answer:
Marc's age is 12
Step-by-step explanation:
Let
x ----> Marc's age
y ---> Tony's age
z ---> Ben's age
we know that
the sum of their ages is 40
so
-----> equation A
Marc is half as old as Tony
so
----> equation B
Marc is three times as old as Ben
so
----> equation C
substitute equation B and equation C in equation A
solve for x
therefore
Marc's age is 12
3 to the 4th power is 81, 3 times itself 4 times.

3^2/3^4
To find the answer, we can use this equation:
a^m / a^n = a^m - n
We can now just use 2 - 4, which equals -2.
Now we have 3^-2
3^-2 in decimal form is 0.11111, which equal to 1/9
