Indices and Logarithms
Logarithms are useful for solving problems involving indices (or exponents). In fact, logarithms are indices written in another form. The definition a^x=b\Longleftrightarrow x=\log_a b is valid when a>0 , a\neq1 and b>0 . Questions involving logarithms occur throughout the course, so it is important to be confident using them.
