• When Is $b^2c^2+c^2a^2+a^2b^2>abc(a+b+c)$ True?
  A sum-of-squares identity proves the expression is at least the right-hand side; equality occurs at a=b=c, so strictness needs an exception.
• How to Solve $8n^2=64n\log_2(n)$
  Divide by 8n to reduce the equation to n = 8 log base 2 of n; it has two positive real solutions, approximately 1.1000 and 43.5593.
