" 14."(2+sqrt(3))^(7)+(2-sqrt(3))^(7)

Prove that (2 +sqrt(3))^(7) +(2-sqrt(3))^(7)=10084 Hence show that 10083 lt ( 2+sqrt(3))^(7) lt 10084 .

Evalute: (2+sqrt(3))^(7)+(2-sqrt(3))^(7)

Evaluate the following: (2+sqrt(3))^(7)+(2-sqrt(3))^(7)

Evaluate the following: (2+sqrt(3))^7+(2-sqrt(3))^7

(2sqrt(7))/(sqrt(5)-sqrt(3))

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)

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) 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)
