If log1087.5 = 1.9421, then the number of digits in (875)10 is? Choose the correct choice from the following choices.
A) 30  B) 28  C) 27  D) 26  E) 25
X = (875)10 = (87.5 x 10)10   Therefore, log10X = 10(log1087.5 + 1)   = 10(1.9421 + 1)   = 10(2.9421) = 29.421   X = antilog(29.421)   Therefore, number of digits in X = 30.   30NSWER:30
