" (iii) "(100)/(81)

Which is the greatest among (3)^(198), (27)^(64), (9)^(100) and (81)^(49) ?

The tens digit of (81)^(100)(121)^(100)-1 is

The tens digit of (81)^(100)(121)^(100)-1 is

Find the value of 1/(81^n)-(10)/(81^n)C_1+(10^2)/(81^n)C_2-(10^3)/(81^n)C_3++(10^(2n))/(81^n) .

sqrt((25)/(81)-(1)/(9))=?(2)/(3)( b) (4)/(9)( c) (16)/(81) (d) (25)/(81)

the value of (1)/((81)^n)-^(2n) C_1. ((10)^2)/((81)^n)+ ^(2n) C_1 ((10)^2)/((81)^n)…....+((10)^2n)/((81)^n) is

Find the value of 1/(81^n)-(10)/(81^n)^(2n)C_1+(10^2)/(81^n)^(2n)C_2-(10^3)/(81^n)^(2n)C_3++(10^(2n))/(81^n) .

Simplify the following by factor method: sqrt(100)+sqrt(81)

Simplify the following by factor method: sqrt(100)-sqrt(81)
