Answer:
B or the second option
Step-by-step explanation:
the rules of math state that you must not have a square root in the denominator so in order to get rid of it multiply the top and bottom by the square root on the bottom. Any square root times itself takes away the square root symbol
1 2 − 1 9 8
The answer is B 62
I just divid 124 by 2
11=y
66=x
6=y
55=x
Hope this helps
Have a great day!
