Multiply ln * x
0.81 = lnx

Solving
0.81 = lnx

Solving for variable 'l'.

Move all terms containing l to the left, all other terms to the right.

Add '-1lnx' to each side of the equation.
0.81 + -1lnx = lnx + -1lnx

Combine like terms: lnx + -1lnx = 0
0.81 + -1lnx = 0

Add '-0.81' to each side of the equation.
0.81 + -0.81 + -1lnx = 0 + -0.81

Combine like terms: 0.81 + -0.81 = 0.00
0.00 + -1lnx = 0 + -0.81
-1lnx = 0 + -0.81

Combine like terms: 0 + -0.81 = -0.81
-1lnx = -0.81

Divide each side by '-1nx'.
l = 0.81n-1x-1

Simplifying
l = 0.81n-1x-1
