log4 + log25 = ?
Take Free Practice Test On 2026 JAMB UTME, Post UTME, WAEC SSCE, GCE, NECO SSCE
Correct Answer: Option A
Explanation:
To solve \( \log 4 + \log 25 \), use the property of logarithms that states \( \log a + \log b = \log (a \cdot b) \).
So:
\[ \log 4 + \log 25 = \log (4 \cdot 25) \]
Calculate \( 4 \cdot 25 \):
\[ 4 \cdot 25 = 100 \]
Therefore:
\[ \log 4 + \log 25 = \log 100 \]
Since \( \log 100 = 2 \) (because \( 100 = 10^2 \)):
The correct answer is:
