Answer 2

Answer:

0.2

Step-by-step explanation:

Remember to always rationalize when you see a root in the denominator. It will always help a lot.

So we know that we can rationalize this fraction by multiplying both numerator and denominator by 3 - 2 root 2. As this will make the identity a^ - b^2 in the denominator. After simplifying, we get (3-2root2)/9-8 which is equal to 3 - 2root2. We know that root 2 is equal to 1.4. After substitution, we get 3- 2.8 = 0.2

Have a nice day !!!
