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
√(474-441)(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.
