please help me to calculate this. I have gotten everything else right but I am confused on calculation. r=6(1853)(21)(516)I can do. It is the denominator that I am having a problem with. Square root[6(79)(21)squared][6(44582)(516)squared] I have worked with this for over to hours and I am exhausted. Please Help:

x^2 = x squared online
From your data:
r=6(1853)(21)(516) = 11,118  10,836 = 282
√(474441)(267492 266256) = √(33)(1236)
I am uncertain as to how much is under the radical. If both, multiply and then find square root. If just one, find square root and then multiply.
I hope this helps.
