Y = 7^(x+5),
X= 7^(y+5),
Take log of both sides:
(y+5)log7 = logX,
Divide both sides by log of 7:
y+5 = logX / log7,
y+5 = logX / 0.8451,
y+5 = 1.183*logX,
y+5 = X^(1.183),
Y = X^(1.18 - 5.
If y=7^(x+5)write the equation for the inverse of y. It must be a y=equation.

CORRECTION.
Y = X^(1.18) - 5.
Y = X^(1.18) - 5.
