Compute : (i) 7.625 X 28.43 (ii) 32.56 X 0.09827 X 0.28

Solution:

(i) Let x = 7.625 X 28.43

Therefore, log x = log 7.625 + log 28.43

= 0.8823 + 1.4538

= 2.3361

Therefore, x = antilog 2.3361 = 216.9

(ii) x = 32.56 X 0.09827 X 0.28

Therefore, log x = log 32.56 + log 0.09827 + log 0.28

= 1.5127 + ‾2.9924 + ‾1.4472

= ‾1.9523

Therefore, x = antilog ‾1.9523 = 0.8960
