Question

Rationlise the denominators of 1/3+root2
​

Answer 1

Answer:

3-root2/7

Step-by-step explanation:

1/3+root2 ×3-root 2/3-root 2

=3-root 2/(3)^2 - (root 2)^2

3-root 2/ 9-2

= 3-root 2/ 7

Answer 2

Answer:

[1/(3+$\sqrt{2}$ )]X [(3-$\sqrt{2}$)/(3-$\sqrt{2}$)

=(3-$\sqrt{2}$)/$3^{2}$-$\sqrt{2} ^{2}$

=(3-$\sqrt{2}$)/(9-2)

=(3-$\sqrt{2}$)/7

Answer is (3-$\sqrt{2}$)/7
