(iii) `(sqrt(2)+1)/sqrt(5)`

Find the value to three places of decimals of each of the following.It is given that sqrt(2)=1.414,sqrt(3)=1.732,quad sqrt(5)=2.236 and sqrt(10)=3.162(2+sqrt(3))/(3) (ii) (sqrt(2)-1)/(sqrt(5))

(sqrt2 + 1)/sqrt5

Find the value of three places of decimals; of each of the following.It is given that sqrt(2)=1.414,sqrt(3)=1.732,sqrt(10)=3.162 and sqrt(5)=2.236( approx ).(sqrt(2)+1)/(sqrt(5)) (ii) (2-sqrt(3))/(sqrt(3))( iii) (sqrt(10)-sqrt(5))/(sqrt(2))

Simplify each of the following : (i)(sqrt(2)+1)/(sqrt(2)-1)+(sqrt(2)-1)/(sqrt(2)+1)" "(ii)(sqrt(5)+sqrt(3))/(sqrt(5)-sqrt(3))+(sqrt(5)-sqrt(3))/(sqrt(5)+sqrt(3))" "(iii)(2)/(sqrt(5)+sqrt(3))+(1)/(sqrt(3)+sqrt(2))-(3)/(sqrt(5)+sqrt(2))" "(iv)(sqrt(7)+sqrt(5))/(sqrt(7)-sqrt(5))-(sqrt(7)-sqrt(5))/(sqrt(7)+sqrt(5))

f(x)=cos^(-1)(x-x^2)+sqrt(1-1/(|x|))+1/[[x^2-1]) then domain of f(x) is (where [x] is G.I.F.) [sqrt(2),(1+sqrt(5))/2] (2) (-sqrt(2),(1-sqrt(5))/2] (sqrt(2),(1+sqrt(5))/2] (4) (1,2)

(1+sqrt(2))/(sqrt(5)+sqrt(3))+(1-sqrt(2))/(sqrt(5)-sqrt(3))

Simplify (sqrt(2)-1+sqrt(6))/sqrt(5)

[ If N=(sqrt(sqrt(5)+2)+sqrt(sqrt(5)-2))/(sqrt(sqrt(5)+1))-sqrt(3-2sqrt(2)) then N equals [ (A) 1, (B) 2sqrt(2)-1 (C) (sqrt(5))/(2), (D) (2)/(sqrt(sqrt(5)+1))]]
