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

anonymous · Answer

is e $$7^{x+3}?$$

anonymous · Answer

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

anonymous · Answer

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

anonymous · Answer

oops ---> y:=7

anonymous · Answer

anonymous · Answer

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