" 7.Simplify: "(2.3^(n+1)+7*3^(n-1))/(3^(n+2)-2((1)/(3))^(1-n))

(2.3^(n+1)+7.3^(n-1))/(3^(n+1)-2((1)/(3))^(1-n))=

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

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

Simplify (6(8)^(n+1)+16(2)^(3n-2))/(10(2)^(3n+1)-7(8)^(n))

Simplify. ((n + 3)!) / ((n^2 - 4) (n +1)!)

Lt_(x to oo) (5.2^(n+1)+2.3^(n+1))/(3.2^(n)-7.3^(n))=

Simplify. (n + 2) / (n!) - (3n + 1) / ((n + 1)!)

The sum of the series (2)/(3)+(8)/(9)+(26)/(27)+(80)/(81)+ to n terms is n-(1)/(2)(3^(-n)-1)(b)n-(1)/(2)(1-3^(-n))(c)n+(1)/(2)(3^(n)-1)(d)n-(1)/(2)(3^(n)-1)

lim_ (n rarr oo) (5.2 ^ (n + 1) + 2.3 ^ (n + 1)) / (3.2 ^ (n) -7.3 ^ (n))

Simplify the following: (5^(n+3)-6x5^(n+1))/(9x5^(x)-2^(2)x5^(n))( ii) (6(8)^(n+1)+16(2)^(3n-2))/(10(2)^(3n+1)-7(8)^(n))
