7.-4+4sqrt(3i)

sqrt(-3-4i)=

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

A line passes through point P(4,5) and makes 30^@ with X-axis. Then the coordinates of the point which is at distance of 4 unit on either side of P is : a. (4-2sqrt(3),7) , (4+2sqrt(3),7) b. (4+2sqrt(3),7) , (4-2sqrt(3),7) c. (4+2sqrt(3),7) , (4-2sqrt(3),3) d. (4-2sqrt(3),7) , (4-2sqrt(3),7)

Simplify : (5+sqrt3)/(7- 4sqrt3) -(5-sqrt3)/( 7+4sqrt3)

What is the value of sqrt(7 + 4sqrt(3))?

What is the value of sqrt(7 + 4sqrt(3))?

if a=(7+4sqrt(3))^(2005) and b=(7-4sqrt(3))^(2005) then (a+1)^(-1)+(b+1)^(-1)

If (7+4sqrt(3))^(x^(2-8))+(7-4sqrt(3))^(x^(2-8))=14, then x=
