Question 9,10 and 11

9. Write each exponential equation in logarithmic form. (For example, the logarithmic form of the exponential equation 23 = 8 is log2 8 = 3.) (a) 62 = 36 _2 . (b) (22) = 10. Simplify the following expressions. (For example, log7(3:y2) = log73: + 2 log? y.) (a) 10g2(3''33f4l (b) ln( W\" ) (use)T 11. Solve each equation. (a) log4 .1: + log4(rr 3) = 1 (b) log(10: + 1) loga: = 2
