Urgent! Proof of Mathematical Analysis in Senior High School
1. Physicochemical molecules: left =6/ (root number 7+ 1), right =6/ (root number 1 1+ root number 5).

Because the number of radicals 7 is less than the number of radicals 1 1, the number of radicals 1 is less than the number of radicals 5, and (the number of radicals 7+ 1) is less than (the number of radicals1+5), so 6/ (radicals

2. Basic inequality: (a+b)≥2√(ab) (premise: a≥0, b≥0)

Just set this formula.
