Log Functions  Exercise 2  Convert Exponentials to Log Form
Convert each exponential statement to log form by using the
property y = a^{x} implies that log_{a}y = x.
Then use your calculator to find x. In the last two problems the
Division Property of Equality is also used.

JUSTIFICATION 
10^{x} = 99
e^{x} = 40
e^{2x} = 40
10^{4x} = 99
