Question
1. 4√2 x 5√2 = 4(1.4)(5)(1,4)=39,2
2. 6√ 8 + 3√8 = 9√ 16=36
3. To convert 6,313131… to a fraction , put f = 6,313131…then 10f = 63,13131… Subtract: 10f – f = 9f and 9f = 60 so f = 60/9  

Answer
Are you just checking your work, since you have answers for each question?  Assuming your teacher doesn't want you to use a calculator and wants the answer in simplest form...

1. 4√2 x 5√2 = 20√4 = 40
2. 6√8 + 3√8 = 9√8 = 9√(4*2)= 18√2
3. convert 6.313131… to a fraction 631/100 =
