Suppose your pocket calculator is damaged: it can only evaluate logarithms of numbers between 0 and 1. Find a way to evaluate the following logarithms with the use of such a calculator.
log2 = log (10*0.2) = log10 + log0.2 = 1 + log0.2
log333 = log(1000 * 0.333) = log10^3 + log0.333 = 3 + log0.333
log1.1 = log(10 * 0.11) = log10 + log0.11 = 1 + log0.11
log7588.56 = log(10 000 * 0.758856) = log10^4 + log0.758856 = 4 + log0.758856
Are these solutions correct?
