Question 306522: which expression is equivalent to log(7)2401 - log(3)243
1) log(4)2158
2) 7 log 2401 - log 243
3) -log(4) 2401/243
4) -1 Answer by dabanfield(803) (Show Source):
You can put this solution on YOUR website! which expression is equivalent to log(7)2401 - log(3)243
Since 7*7*7*7 = 7^4 = 2401, log(7)2401 = 4
Also 3*3*3*3*3 = 3^5 = 243, so log(3)243 = 5
The expression above then reduces to 4 - 5 = -1
