if log 2 = 0.30103 and log 3 = 0.4771, find the number of digits in (648)5  Choose one:
A) 14.05
B) 14.02
C) 277
D) 288
E) 222
log(648)5   = 5 log(648)   = 5 log(81 × 8)   = 5[log(81) + log(8)]   =5 [log(34) + log(23)]   =5[4log(3) + 3log(2)]   = 5[4 × 0.4771 + 3 × 0.30103]   = 5(1.9084 + 0.90309)   = 5 × 2.81149   ≈ 14.05   14.05nswer: 14.05
