Question

log(10^(5)x^(3))=
A. 15
B. 5x^3
C. 5+3log(x)
D. 15log(x)

Answer 1

use these two properties of logs:
1. \(\large log_bM^n=nlog_bM \)
2. \(\large log_b(M\cdot N)=log_bM + log_bN \)

Answer 2

i was thinking it was C or D

Answer 3

since you have to use the second property, you know you have to have addition... unless it can be simplified.....

Answer 4

so its C?

Answer 5

Answer 6

the 10^5 log(10^5 x^3)
