3^p  × 3^(−1)  × 5 × 3^(p−1)  = 2 × 3^4    3^(p−1+p−1) ×5=2×3^4   3^(2p−6) =(2/5)  log(3^(2p−6) )=log((2/5))  (2p−6)log 3=log 2−log 5  2p−6=((log 2−log 5)/(log 3))  p=(1/2){((log 2−log 5)/(log 3))+6}  p=(1/2){((log 2−log 5+6log 3)/(log 3))}  p=((log 2−log 5+6log 3)/(2log 3))  p=((log 2−log 5+log 3^6 )/(log 3^2 ))  p=((log(2×3^6 ÷5))/(log 9))=((log(((1458)/5)))/(log 9))≈2.5830
