ln(x^2 - 5)=0

I did it this way.. e^(ln[x^2 - 5])=e^0

x^2 - 5=1

x^2 = 6

which x = the square root of 6.

Would anyone kindly check this to see if I did it correctly? Thank you!

you work is correct.

but u missed a solution.

not that if $\displaystyle x^2=6$ then we have $\displaystyle x=\pm\sqrt{6}$. - Nov 21st 2006, 06:49 PMThePerfectHacker
