P1(P2V2T1/T2P1) power n = P2V2 POWER N
I will suggest that you have to take an 1/n to both sides because form this there will no effect on your equation.
after that you will say that at the left side you will be get rid of power n. and your equation will be re-arrange like
P1 Power 1/n (P2V2T1/T2P1)= P2 Power 1/n x V2
1/T2= P2 power 1/n x v2 x p1/p1 Power 1/'n x P2V2T1
t2 = p1power 1/nxp2v2t1 / p2 power 1/n x v2 x p1
