 But as $$10$$ is no longer the basis, one cannot multiply by $$100$$ or $$1000$$ by merely adding $$2$$ or $$3$$ to the index. One can change the natural logarithm to the ordinary logarithm simply by multiplying it by $$0.4343$$; or

and conversely,

Exponential and Logarithmic Equations.

Now let us try our hands at differentiating certain expressions that contain logarithms or exponentials.

Take the equation:

First transform this into
