(7+3sqrt5)/(7-3sqrt5)=

The value of frac (7+3sqrt 5)(3 + sqrt 5)+frac(7 - 3sqrt 5)(3 - sqrt 5) lies between: frac (7 + 3 sqrt 5) (3 + sqrt 5) + frac (7 - 3 sqrt 5) (3 - sqrt 5) का मान के बीच है:

tan^(2)((1)/(2)sin^(-1)(2)/(3))= (A) (7+3sqrt(3))/(2) (B) (7-5sqrt(3))/(2) (C) (7-3sqrt(5))/(2) (D) (7+5sqrt(3))/(2)

The square root of (7 + 3sqrt5) (7 - 3sqrt5) is :

it [[3.5, x7, x, 7x, 5.3]] = 0

Show that the points P(7,3) , Q ( 6,3+ sqrt3) and R (5,3) from an equilateral triangles.

Let A = {3, pi , sqrt(2) , - 5,3 + sqrt(7),2//7} . The subset of A containig all the elements from it which are irrational number is :
