\[8=2^{x+4}\]

OpenStudy (anonymous):

first subtract 4 from both sides

OpenStudy (anonymous):

8=2x+4 X=2

OpenStudy (anonymous):

i need help solving the second equation i tryped it wrong at first

OpenStudy (anonymous):

then you would find how many times 2 goes into 4, which is 2, so x=2

OpenStudy (anonymous):

yes, 2^2=

OpenStudy (anonymous):

oohh im sorry i realize now

OpenStudy (anonymous):

x=-2

OpenStudy (anonymous):

-2+4=2, then 2^2=4

OpenStudy (mathmale):

Best if we were to start over. I am interpreting your equation as an exponential one: \[8=2^{x+4}\]The base is 2 and the exponent / power is x+4.
