We can use the property of logarithms to solve this problem.

ln(8x)=7 is in logarithmic form

We need to transform it into exponential form like this

Change ln%28x%29=y into b%5Ey=x

So we can do this knowing that the base of the natural log ln is e:

e%5E7=8%2Ax

e%5E7%2F8=x which would be the exact answer, but to see an approximation

1096.633158%2F8=x

x=137.0791448 final answer approximation
