Note:



Take the natural log of both sides (actually, any base will do as long as you use the same base on both sides of the equation)



Use to write:



Multiply both sides by the reciprocal of



terms on the left, constants on the right, just like any other single variable equation.



Factor out



Multiply by the reciprocal of the coefficient on



The rest is just calculator work.
