If log10 2 = 0.3010, the value of log10 80 is: Choices:
A) 2.65
B) 1.903
C) 3.05
D) 6.487
E) 5.98
Explanation:   log10 80	= log10 (8 x 10)   = log10 8 + log10 10   = log10 (23 ) + 1   = 3 log10 2 + 1   = (3 x 0.3010) + 1   = 1.9030.   answer 1.903
<result>B</result>
If log10 2 = 0.3010, the value of log10 80 is:
