If Log102 = 0.3010 and Log103 = 0.4771, evaluate Log104.5
A
0.9542
B
0.6532
C
0.4771
D
0.3010
Verified Correct Answer: B.
Step-by-Step Mathematical Solution
Log102 = 0.3010 and Log103 = 0.4771
Log104.5 = Log1041/2
= Log109/2
= Log109 - Log102
= log1032 - Log102
= 2Log103 - Log102
= 2(0.4771) - 0.3010
= 0.9542 - 0.3010
= 0.6532
