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

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

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