(11^((1)/(2)))/(11^((1)/(a)))

Simplify : (i) 2^(2//3).2^(1//5) (ii) ((1)/(3^(3)))^(7) (iii) (11^((1)/(2)))/(11^((1)/(4))) (iv) 7^(1//2).8^(1//2)

Simplify : (11^((1)/(2)))/( 11^((1)/(4)))

Simplify (11^(1/2))/(11^(1/4))

The integral int(sec^(2)x)/((sec x+tan x)^((9)/(2)))dx equals (for some arbitrary constant K)-(1)/((sec x+tan x)^((11)/(2))){(1)/(11)-(1)/(7)(sec x+tan x)^(2)}+K(1)/((sec x+tan x)^((11)/(2))){(1)/(11)-(1)/(7)(sec x+tan x)^(2)}+K-(1)/((sec x+tan x)^((11)/(2))){(1)/(11)+(1)/(7)(sec x+tan x)^(2)}+K

Which of the following is equal to 1?((0.11)^(2))/((1.1)^(2)xx0.1) (b) ((1.1)^(2))/(11^(2)xx(0.01)^(2)) (c) ((0.011)^(2))/((1.1)^(2)xx(0.01)^(2)) (d) ((0.11)^(2))/(11^(2)xx0.01)

The sum (((11),(0)))/1+(((11),(1)))/2+(((11),(2)))/3+.........+(((11),(11)))/12equals (where ((n),(r)) denotes nC_r)

(.1^(11)C_(0))/(1)+(.^(11)C_(1))/(2)+(.^(11)C_(2))/(3)+....+(.1^(11)C_(10))/(11)

(11C_(0))/(1)+(11C_(1))/(2)+(11C_(2))/(3)+......+(11C_(10))/(11)=
