Since you use log rather than ln, I assuming base 10 (common) logs.
Logrithms are exponents!!!!!
They are the exponent you hang on the base to get the number in question. That is, saying log x = y is the same as saying 10^y = x.
So log x = -2 is the same as saying 10^(-2) = x or x = 1/100.

When using log, it is in base 10.
log a = b can be written as 10^b=a
So log x = -2 can be written as 10^(-2) = x
Therefore x = 1/(10^2) = 1/100

log(x^2)=2log(x) 2log(x)=log(x)^2 means log(x)[2-log(x)]=0. Thus either log(x)=0 or log(x)=2 If log(x)=0 then x=1. If log(x)=2 then x=100

log x = -2
This is read as "The logarithm of x with base 10 is equal to -2."
This can also be read as "10 raised to the -2 power equals x."
Therefore, 10^-2 = 1/100 = 0.01 = x.

assuming there is no base to worry about
log(x) = -2
inverse log both sides
x = 10^-2
x = .01

log (base) x= -2
therfore
x= base^-2
this base can be 10 or any number

log x = -2
convert into exp. form:
x = 10^-2
x = 0.01

log a = b <=> a=e^b
therefor x=e^-2=0.1353...
(presuming this is the natural logarithmus; the process is the same anyway).
