<PRE><B>Question 1043210</B>
Could you help me solve this please?

a) 9^(7-3x) =5
(7-3x)*log(9) = log(5)
7-3x = log(5)/log(9)
7-3x = 0.7325
3x = 6.2675
x = 2.0892
------------------------
b) log0.135 
is the answer -0.8696
Yes, or -0.8697 if you round off
-----------------------------------
 
c) log(7,22) = log7(22) = log(22)/log(7) = 1.588
is the answer: 1.588
