Logarithms Exercise 9.1 Question 1. Convert the following to logarithmic form: (i) 52 = 25 (ii) a5 =64 (iii) 7x =100 (iv) 9° = 1 (v) 61 = 6 (vi) 3-2 = (vii) 10-2 = 0.01 (viii) (81) = 27 Solution: Question 2. Convert the following into exponential form: (i) log2 32 = 5 (ii) log3 81=4 (iii) log3 = -1 (iv) log3 4= (v) log8 32= (vi) log10 (0.001) = -3
ML Aggarwal Solutions for Class 9 Maths Chapter 9 – Logarithms (iii) if log 10 P = 2a + b/2 – 3c, express P in terms of x, y and z. Solution: Given: log 10 x= a (10)a = x log 10 y = b (10)b = y log 10 z =c (10)c = z (i) Write down 102a-3 in terms of x. 102a-3 = (10)2a / (10)3 = (10a)2 / (10 × 10 × 10) Substitute the value of (10)a = x, we get
