If log10 2 = 0.3010, the value of log10 80 is:

1.

If log₁₀ 2 = 0.3010, the value of log₁₀ 80 is:

[A].	1.6020
[B].	1.9030
[C].	3.9030
[D].	None of these

Answer: Option B

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.
