If log1087.5 = 3.9421, then the number of digits in (875)10 is? Choose the correct choice from the following options:
A) 30 B) 28 C) 27 D) 50 E) 25
X = (875)10 = (87.5 x 10)10   Therefore, log10X = 10(log1087.5 + 1)   = 10(3.9421 + 1)   = 10(4.9421) = 49.421   X = antilog(49.421)   Therefore, number of digits in X = 50.   ANSWER:50
