Return Early Pattern for Functions -- Question about it

JavaScript
1

I already finished the challenge and understood it fine… My question is:

WHAT IN THE HELL IS THE MATH PART AT THE BOTTOM FOR?? YOU KNOW, THE PART THAT SAYS–>

" return Math.round(Math.pow(Math.sqrt(a) + Math.sqrt(b), 2)); "

Your code so far

// Setup
function abTest(a, b) {
  // Only change code below this line
  if (a<0 || b<0){
    return undefined
  }
  
  
  // Only change code above this line

  return Math.round(Math.pow(Math.sqrt(a) + Math.sqrt(b), 2));
}

// Change values below to test your code
abTest(2,2);
