1/Log3 60 + 1/Log4 60 +1/ Log5 60 = ____?
- 1
- 2
- 5
- None
Explanation
1/log3(60) + 1/log4(60) + 1/log5(60)
= log60(3) + log60(4) + log60(5) (using the change of base formula)
= log60(3×4×5) (using the product rule of logarithms)
= log60(60)
= 1 (since log60(60) is equal to 1)
So the correct answer is: 1
