I think I figured it out.
85/2=42.5
log5=log42.5
log42.5/log5
=2.330 to the third decimal
How do you solve this exponential equation using logarithms?
2*5^x=85
Do you start like this?
xlog2*5=log85
I don't know what to do after that.

2^5x = 85
Log2^5x = log85
5xlog2 = log85
Solve for x
x = log85/5log2
Log2^5x = log85
5xlog2 = log85
Solve for x
x = log85/5log2
