Remember:
log[a]x=y
x=a^y
.
1)
log[10]x=3.8893
x=10^3.8893
x=7749.97
.
2)
log[10]x=-1.5003
x=10^-1.5003=1/10^1.5003
x=.031601

You don't quite have the right idea. Always remember
"logs are exponents" end of story.
So, when you see log(result) =
Whatever is on the other side of the "=" sign is the exponent
The (result) is what you get when you raise the base to that exponent
Let's look at the 1st problem
log(result) = 3.8893
If 3.8893 is the exponent, and the base is 10, I get
since the (result) is
I get
------------------
2nd problem
log(result) = - 1.5003
