So I'm studying norm of matrices in my calc class, and most resources I've looked at seem like it's just the square root of all the entry values over the sum of all the entries, but when given the matrix(adsbygoogle = window.adsbygoogle || []).push({});

[1 3]

[0 1]

Sqrt((11+sqrt(117))/2)

The 11 is the sqrt of 1^{2}+ 3^{2}+ 1^{2}

the 2 is the root of 1 + 3 + 1, where does the plus sqrt(117) come from?
