well u can use- (integral) a^x dx= a^x/lna +c but since there is a function in the power u can use substitution u=2x+1 and then go forward!

y= [e^ln(7)]^ (2x+1)

= e^[ (2x+1) ln(7) ]

Integrating

1/[2ln(7)] e^(2x+1)ln(7) ]

= 1/[2ln(7)] * y

= 1/ [2ln(7) ] 7^(2x+1)+C

spiral knows his shit br8.
I am sure he does.

My point was that OP would have learnt better from an explanation, rather than just the final answer. The matter is not whether Spiralflex 'knows his shit' or not, but whether he could have explained it, which again I am confident he can.

You know me. :) Never leave stuff unexplained. I have a habit of typing the answer first then editing it.

spiral always provides solutions, I should have said.

One thing he has left unexplained is his GF(real or imaginary)
