Here is your answer
$( 3 - \sqrt{2} ) \div (3 + \sqrt{2} ) \\ = (3 - \sqrt{2} )(3 - \sqrt{2} ) \div (3 + \sqrt{2} )(3 - \sqrt{2} ) \\ = (9 - 3 \sqrt{2} - 3 \sqrt{2} + 2) \div 3 {}^{2} - ( \sqrt{2} ) {}^{2} \\ =( 11 - 6 \sqrt{2} ) \div (9 - 2) \\ = (11 - 6 \sqrt{2} ) \div 7$
Hope it helps you

reddymudecom: sir you answer this question find the value of k,if x=2,y=1is a solution of the equation 2x+3y=k.

MonarkSingh: you put these values and find k

MonarkSingh: k =2x2 +3x1 = 4+3 =7

reddymudecom: thanks sir I wrote already

reddymudecom: one of the angles of a triangle is 50°and the other two angles are equal.Find the measure of each of the equal angles

MonarkSingh: x+x+50 = 180. 2x=180-50. x =130/2. x=75

reddymudecom: if x+6 is a factor ofp(x) =x cube +3x square+ 4x+k,find the value of k.

MonarkSingh: x+6=0. x=. -6. put it in Equation
