(5times25^(n+1)-25times5^(2n))/(5times5^(2n+3)-(25)^(n+1))

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

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))

The value of (5.(25)^(n+1) + 25.(5)^(2n-1))/(25.(5)^(2n) -105(25)^(n-1)) is :

5^(2)times25^(3)times625=(5)^(?)

Find n,if 12times^((n-1))P_3=5times^((n+1))P_3

[8^(-2/3)times2^(1/2)times25^(-5/4)]÷[32^(-2/5)times125^(-5/6)] =sqrt2

Find the value of n : (2^(3)xx5^(n+1)xx10^(2)xx5^(n-1))/(125xx5^(n-2)xx2^(7))=(25)/(4)

lim_ (n rarr oo) (2.5 ^ (n + 1) -3.7 ^ (n + 1)) / (2.5 ^ (n) + 3.7 ^ (n)) =

Simplify: (i) (10xx5^(n+1)+25xx5^n)/(3xx5^(n+2)+10xx5^(n+1)) (ii) ((16)^7xx(25)^5xx(81)^3)/((15)^7xx(24)^5xx(80)^3)
