Question 755373: If 3^x = 7, which is true?
(a) x = log_7 (3)
(b) x = log_3 (7)
(c) 3 = log_x (7)
(d) 7 = log_3 (x)
(e) 7 = log_x (3) Answer by lwsshak3(11628) (Show Source):
You can put this solution on YOUR website! If 3^x = 7, which is true?
(a) x = log_7 (3)
(b) x = log_3 (7)
(c) 3 = log_x (7)
(d) 7 = log_3 (x)
(e) 7 = log_x (3)
***
3^x = 7
This is a definition of logs in exponential form:
Base(3) raised to log of the number(x)=number(7)
so (b) is the right answer
