### Minimum value

Determine the minimum value of
$\frac{4x^3}{y}+\frac{y+1}{x}$

with $x>0$ and $y>0$ real numbers.

### Re: Minimum value

Apparently, the denominators should be 1. So the minimum value will be 6.

### Re: Minimum value

No.
If, X>0, y>0
Then, it could be x=y=0.1 or 0.01 or 0.000001
Because, x and y are real number.

I don't think so. Bcoz, x>0 and y>0 are real numbers not natural.

I know the difference.

What I meant was: in the solution to the problem, both $x$ and $y$ should be 1.

BTW, this is just an observation since I didn't go through with the solution; it is an "apparent result".
The text passage contains a mathematical question and multiple responses attempting to solve it. The question asks for the minimum value of a given expression with certain constraints on the variables.
