# Math Help - Exponential Equations

1. ## Exponential Equations

$2^x+2 - 2^x =48$

***NOTE*** THE + 2 IS ALSO ON THE EXPONENT!!!

So many things run through my head when I think about this? Can any of you break this down for me? Mucho appreciation guys!

2. $2^{x+2} - 2^x =48$

Using index laws

$2^{x}2^{2} - 2^x =48$

Now factoring

$2^{x}(2^{2} -1) =48$

$2^{x}(4 -1) =48$

$3\times 2^{x} =48$

You got it from here?
