1, log_a(MN=log_a(M)+log_a(N): this is the log_alog_a(M)-log_a(N) that multiplies two numerical values and converts them into logarithm, and this is the subtraction log_a(N) that divides two numerical values and converts them into logarithm.
2. log _ a (m) =1/log _ a (1/m): this is to find the reciprocal of a numerical value and convert it into the reciprocal of a logarithm. Log_a( 1)=0: This is a special property of logarithmic function, and the zeroth power of any number is equal to 1. These formulas are widely used in mathematics and physics, which can help us simplify complex calculations and deal with large-scale data.
