I would like help to solve this what i did was to take away the square root i squared both sides coming up with

(ln sqrt(x-8))^2= (5)^2

ln(x-8)=25

am i alowed to do this with ln in the equation?

then i subtract 8 from both sides

ln x = 17

e^(ln x)= e^17

e cancels out ln leaving with

x=e^17

this is not right the real answer is

x = 8 + e^10 on math-way but how?

thanks

Exponential form:

e^5 = sqrt(x-8)

Square both sides:

e^10 = x-8

X = 8 + e^10

exponential form:
