We can use the laws of logarithms to manipulate expressions and solve equations involving logarithms, as the next two examples illustrate. Worked example 2.8 If xalog 10 and yb, express log 10 100a2 b in terms of x, y and integers. Use laws of logs to isolate log 10 a and log 1 0 b in the given expression. First, use the law about the logarithm ...
