If log102 = 0.3010, log10 3 = 0.4771, then the number of zeros between the decimal point and the first
significant figure in (0.0432)10 is?
Choose the correct choice from the following:
A) 10
B) 13
C) 14
D) 15
E) 16
X = (0.0432)10 = (432/10000)10 = (33.24/104)10   Therefore, log10X = 10 (log103 + 4log102-4)   = 10(1.4313 + 1.2040 - 4)   = 10(-1.3647)   = -13.647   = -14.353   Therefore, X = antilog(-14.053)   Thus, number of zeros between the decimal and the first significant figure = 13   ANSWER:13
