Question

Enter the number that
goes beneath the
radical symbol.
(-1,-3)

Answer 1

50

Explanation:

`\boxed{distance \: between \: 2 \: points = \sqrt{(y1 - y2)^(2) + (x1 - x2) {}^(2) }}`

Distance between the 2 points

`= \sqrt{( - 3 - 2) {}^(2) +( - 1 - 4) {}^(2) }`

`= \sqrt{( - 5)^(2) + ( - 5)^(2) }`

`= √(25 + 25)`

`= √(50)`

Thus, the number that goes beneath the radical symbol is 50.
