Is it\[10^{x+4} = 1000\] In anyway case, it's just like the last one, you can solve this one in a minute ;)

10^x+4=1000
10^x = 996
x = log 996
2.9982

No, you solved it correctly if the +4 is not in the exponent

be careful of what you're solving... which of these is the correct expression on the left:
\[\large 10^{x+4} \]
or
\[\large 10^{x}+4 \]

then like @dpflan , said, you need to resolve... your original solution is for the second expression

10^(x + 4) = 1000
x + 4 = 3
x = 1

Well, it currently have no fractional value, nothing passed the decimal point, so you can rewrite that \[1=1.00000....\]
