" (i) "(2+sqrt(2))^(2)

[ 8- ((4^(9/4 ) sqrt(2.2 ^2))/( 2 sqrt( 2^(-2))))^(1/2) ] is equal to

Examine,whether the following numbers are rational or irrational: (2-sqrt(2))(2+sqrt(2)) (ii) (sqrt(2)+sqrt(3))^(2)

If (0,1),(1,1)a n d(1,0) be the middle points of the sides of a triangle, its incentre is (2+sqrt(2),2+sqrt(2) ) (b) [2+sqrt(2),-(2+sqrt(2))] (2-sqrt(2),2-sqrt(2)) (d) [2-sqrt(2),(2+sqrt(2))]

If (0,1),(1,1)a n d(1,0) be the middle points of the sides of a triangle, its incentre is (2+sqrt(2),2+sqrt(2) ) (b) [2+sqrt(2),-(2+sqrt(2))] (2-sqrt(2),2-sqrt(2)) (d) [2-sqrt(2),(2+sqrt(2))]

If (0,1),(1,1) and (1,0) be the middle points of the sides of a triangle,its incentre is (2+sqrt(2),2+sqrt(2))( b) [2+sqrt(2),-(2+sqrt(2))](2-sqrt(2),2-sqrt(2)) (d) [2-sqrt(2),(2+sqrt(2))]

((2-sqrt(2))(2+sqrt(2)))/(4-2sqrt(2))

(2+sqrt(2)+(1)/(2+sqrt(2))+(1)/(sqrt(2)-2)) simplifies to 2-sqrt(2)(b)2(c)2+sqrt(2)(d)2sqrt(2)

simplify ({sqrt(3)}-2{sqrt(2)})/({sqrt(3)}^(2)-2{sqrt(2)}^(2))

The value of (2+sqrt(2))(2-sqrt(2)) is:

Evaluate (sqrt(2)+sqrt(2)+sqrt(2))^2
