" (i) "(3^(n)times9^(n+1))/(3^(n-1)times9^(n-1))

(3^nxx9^(n+1))/(3^(n-1)xx9^(n-1))

Simplify the following: (i)\ (3^n\ xx\ 9^(n+1))/(3^(n-1)\ xx\ 9^(n-1)) ,

Simplify the following: (3^(n)x9^(n+1))/(3^(n-1)x9^(n-1)) (ii) (5x25^(n+1)-25x5^(2n))/(5x5^(2n+3)-(25)^(n+1))

Simplify: (3^(n+1))/(3^(n(n-1)))-:(9^(n+1))/((3^(n+1))^((n-1)))

(5^(n+3)-6times5^(n+1))/(9times5^(n)-2^(2)times5^(n))

Fnd the value: ((243)^((n)/(5))3^(2n+1))/(9^(n)*3^(n-1))

(3xx9^(n+1)-9xx3^(2n))/(3xx3^(2n+3)-9^(n+1))

Simplify : (3xx9^(n+1)-9xx3^(2n))/(3xx3^(2n+3)-9^(n+1))
