i think e, f and a can someone check if im correct ?

OpenStudy (anonymous):

is e \[7^{x+3}?\]

OpenStudy (anonymous):

no its the 7^3+x i had got that answer as well but its not an answer choice @Redcan

OpenStudy (anonymous):

humm... well i only see\[7^37^x=y^{(x+3)}=343*7^x\], since \[49^{3x}=7^{2*3x}\]

OpenStudy (anonymous):

oops ---> y:=7

OpenStudy (anonymous):

so 49^3x shouldnt be an answer ? @Redcan

OpenStudy (anonymous):

It's not \[{2\cdot 3x} \ne x+3\]

OpenStudy (anonymous):
