<PRE><B>Question 242841</B>
I need help solving this problem: solve for x: 28^x=10^(-3x) I really need to understand this. Please show and explain all steps.
--------------------------------
28^x=10^(-3x)
-------------
Take the log of both sides to get:
x*log(28) = -3x
---
3x + x*log(28) = 0
---
Factor:
x(3+log(28)) = 0
x = 0 
===========
