I not no who you do this man
20 and 2/3 is correct, I think
I will assume that everything after the radical sign is under the sign...
6√(64x^4y^2)
6√(8^2(x^2)^2(y^2)) removing all of the perfect squares...
6*8*x^2*y
48x^2y
2 3/8 x 1/3 I believe? First you need to change 2 into a 16 then add that into 3 which is 19/8. You multiply across with 1/3 like with numerator with numerator and denominator with denominator. That then equals:19/24. You can't estimate it because 19 is a prime number.
I believe it's one of the four in photo.
