8=3^7x-1
I am taking this as
. If this assumption is not correct, please tell me and i will correct the answer.
Taking logs of both sides of this, using log base 10, gives =log(3^{7x-1}) "This is the rendered form of the equation. You can not edit this directly. Right click will give you the option to save the image, and in most browsers you can drag the image onto your desktop or another program.")
Using log laws, this can become
=log(3)\cdot%20(7x-1) "This is the rendered form of the equation. You can not edit this directly. Right click will give you the option to save the image, and in most browsers you can drag the image onto your desktop or another program.")
Dividing both sides by log 3 gives
}{log(3)}=7x-1 "This is the rendered form of the equation. You can not edit this directly. Right click will give you the option to save the image, and in most browsers you can drag the image onto your desktop or another program.")
Then, simply divide both sides by 7 then add 1 to both sides to become /log(3)}{7}+1=x%20\approx%201.270%20(4sf) "This is the rendered form of the equation. You can not edit this directly.
