Simplify in given form

`( 4 + sqrt(2) )/( 2 + sqrt(2 )) = a - sqrt(b)`

Simplify : ((2 sqrt(45) + 3 sqrt(20)))/(2sqrt5)

Simplify the following term (2+sqrt(8))/(sqrt(2)+sqrt(6))

The simplified form of ( 2)/(sqrt(7) + sqrt(5)) + (7)/(sqrt(12)- sqrt(5)) - (5)/(sqrt(12) - sqrt(7)) is

Simplify : sqrt(192) - 1/2 sqrt(48) - sqrt(75) .

Simplify : sqrt(3+2sqrt(2))

Simplify (3 + sqrt(3))(2+sqrt(2))^(2) .

4. . simplify (4+sqrt(2))(4-sqrt(2))

Simplify: sqrt(3-2sqrt(2))

[(1)/(sqrt(2)+sqrt(3)-sqrt(5))+(1)/(sqrt(2)-sqrt(3)-sqrt(5))] in simplified form equals (a) 0 (b) (1)/(sqrt(2)) (c) 1 (c) sqrt(2)
