HELP !!!!!!!!! I dont understand this.

Answer:
1
Step-by-step explanation:
I dont have the symbol for square root so I'll use % symbol
%12 = % 2 *% 6
%10 = % 2*%5
At the top and bottom we find %2 so it is cancelled
And you only have %6/%5
Now lets multiply with the other fraction
%6*%5 = %30 (nominator is %30)
%5* %6 = %30 (denominator is %30)
So the result is 1
