If `sqrt(5)=2. 236` , then the value of `1/(sqrt(5))` is (a) .367 (b) .447 (c) .745 (d) None of these

If sqrt(5)=2.236 then simplify sqrt((sqrt(5)-1)/(sqrt(5)+1))

If sqrt(5)=2.236, then the value of (sqrt(5))/(2)-(10)/(sqrt(5))+sqrt(125) is equal to (a) 5.59(b)7.826(c)8.944 (d) 10.062

If (1-tan^(2)36^(@))/(2)=sqrt(a)-sqrt(b) ,then the value of (a+b) is equal to (a,b in N) (A)5 (B) 9 (C) 7 (D)None of these

If sqrt 5= 2.236 , then frac(sqrt5) (2) is (A) 1.118 (B) 1.851 (C) 2.236 (D) 1.782

Given that sqrt(3)=1.732 and sqrt(5)=2.236 then find the value of ((6)/(sqrt(5)-sqrt(3))) .

The value of sqrt(6+sqrt(6+sqrt(6+))) ..........is (a) 4 (b) 3 (c) -2 (d) 3.5
