Please explain in words the step-by-step process to find the solutions:

4. Solve the logarithmic equations using algebra and the properties of logarithms. Find exact. so- lutions. Do not estimate. Note: a graph will not serve as justication for you answer, although it might be useful to check your answer. (a) 1033291) = I (b) logx+log(:c-3)=1 (c) (In 1P)2 - 61hr = 16 (Hint: Begin with the substitution u = in r.)
