5^-2x=3 it says solve for x and use natural log where ever log is needed the answer is -ln3/2ln5 I have all the log properties in front of me and still cant make sense of this stuff!

Question

anonymous · Answer

take the ln of both sides
you should get
-2x*ln(5)=ln(3)

This is because when you take log or ln, you can move the exponents down to the front and multiply them

so solve equation:
-2x = ln3/ln5
x= ln3/(-2*ln5)
