algebra solving log equations

posted by on .

n sqrt(x-8)= 5

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


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

this is not right the real answer is
x = 8 + e^10 on math-way but how?


  • algebra solving log equations - ,

    Ln sqrt(x-8) = 5

    Exponential form:
    e^5 = sqrt(x-8)
    Square both sides:
    e^10 = x-8
    X = 8 + e^10

    exponential form:
