`( 4 + sqrt (-3))/(4 - sqrt ( -3))`

Streamline (6-4sqrt (3)) / (6 + 4sqrt (3))

The value of (4+3sqrt(3))/(7+4 sqrt(3)) is

(sqrt(8)-sqrt(3))(-4+sqrt(3))

The value of sin(pi/3-sin^(-1)(4/5)) is (a) (3sqrt(3)-4)/(10) (b) (3sqrt(3)+4)/(10) (c) (4sqrt(3)-3)/(10) (d) (4sqrt(3)+1)/(10)

The value of {1/((sqrt(6) - sqrt(5))) + 1/((sqrt(5) + sqrt(4))) + 1/((sqrt(4) + sqrt(3))) - 1/((sqrt(3) - sqrt(2))) + 1/((sqrt(2) - 1))} is :

In an equilateral triangle,three coins of radii 1 unit each are kept so that they touch each other and also the sides of the triangle.The area of the triangle is (fig) 4:2sqrt(3)(b)6+4sqrt(3)12+(7sqrt(3))/(4) (d) 3+(7sqrt(3))/(4)

If a=sqrt((7+4sqrt(3))/(7-4sqrt(3))) then the value of [a(a-14)]^(2) is
