Online "^" is used to indicate an exponent, e.g., x^2 = x squared.
I assume r1 = r^1 = r to the first power = r.
e = 1 - r - y
Add y and subtract e from both sides.
y = 1 - r - e
Insert values and solve.
The efficiency e of a gasoline engine as a function of its compression ratio r is given by e =1− r1−γ , where γ is a constant.
Find γ for e = 0.55 and r = 7.5.
