    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

    wait, if it's \[10^{x+4}\] then you need to re-solve

    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 \[-1=-1.00000....\]
