im soo confused

"If log10 5 = .70," then we are taking the log, base 10, of 5, which is 0.698970004. I assuming you are rounding.
So, from "log10 5 = .70" we only know that the log is base ten. That's it. So, how do you "find log10 .04?????????"
All that is being asked is to find the common log--log base 10--of 0.04. Using google or any scientific calculator, the log(base10) of 0.04 is -1.39794001.
Don't overthink it!
P.S.: Here's an afterthought. I don't know if it will help, but...
Since 0.04 is 5⁻², log 0.04 = log 5⁻² = (-2)log 5 = (-2)(.70) = -1.4. So, if you didn't have a calculator, or log tables, or google, or any other way to calculate the log of something, you could, as we has just seen, figure out the log of 0.04 to be -1.4, given that the log of 5 was 0.70. Hope that helps!

you can plug that into you calculator and get the value. i ended up with -1.4
