Hi
Need to be familiar with the Properties of Logarithms

*[tex \large \ \ \ \ \ \ \ log_b(x) \ = \ y \ \ \Rightarrow\ \ b^y = x]
*[tex \large\ \ nlog_bx = log_b(x^n) ]
*[tex \large\ \ log_bx + log_by = log_b(xy) ]
*[tex \large\ \ log_bx - log_by = log_b(x/y) ]
In this example: If I am understanding properly..
*[tex \LARGE\ \ \ \ \ \ \ log_3 (1/243)  \ = \ -5 \ \ \Rightarrow\ \ 1/3^5 = 1/243]
 *[tex \LARGE\ \ \ \ \ \ \ log_3 (1/243)  \ = \ -5]
