What is the value of log base 2 of 32 plus log base 2 of 4?
A
7
B
8
C
9
D
6
Correct Answer: Option A — 7
Explanation:
log₂(32) + log₂(4) = 5 + 2 = 7 using the property logb(x)+logb(y)=logb(xy) = log₂(128) = 7. Alternatively compute directly: 2⁵=32 so log₂(32)=5 and 2²=4 so log₂(4)=2. Logarithm addition and the change-of-base formula are frequently tested in competitive exam algebra sections.
