There are four rational numbers 3, - 5, 7 and 13. How to calculate 24

I've thought about it for a long time. Answer: the square of 3 + 7 + 13 + (- 5) = 24-

Use rational number 2; - 5; 7; - 13 to calculate 24 points
Each number can only be used once for four operations of addition, subtraction, multiplication and division

-（-5+7）-（2*（-13））=24

Using 3,4, - 6,10 four rational numbers to calculate 24 points
(we must use all of them. We need three formulas. More is better.)

(10+4-6)*3=24

2, - 3,4, - 5,6 choose 4 numbers, use rational number operation, 24 points
