please answer thw question below

3. Change exponential expressions to logarithmic expressions and vice versa a. 2 =m b. a* =24 c. loga 4=25 d. loge b=3 e. log4 = -3 64 4. Finding the exact value of a logarithm (a) If log 2 8 = y (3) (b) If logs 25 = y (3) log4 64 = y (3) (d) log 1/2 - = X 1 (3) (e) log 7 =1 (7) (f) log, 5' = 3 (5) (g) log2 x = 8(256) (h) logs x = -2 (1/25) (i) log 25 X = NI - (5) 5. Write each expression in terms of x, y and z Vx- +1 (a) log xvx- +1 (b) log a loga (x- 1)3 (x + 1)4 (d) log b xy (e) log xy Z Z
