Simplufy Log_{10}4 + Log_{10}25
- A.
1 - B.
2 - C.
3 - D.
4 - E.
5
Correct Answer: Option B
Explanation
Log_{10}4 + Log_{10}25 = Log_{10}(4 + 25)
= Log_{10}100 = Log_{10}10^{2}
= 2Log_{10}10 = 2 x 1 = 2
Log_{10}4 + Log_{10}25 = Log_{10}(4 + 25)
= Log_{10}100 = Log_{10}10^{2}
= 2Log_{10}10 = 2 x 1 = 2
