Original solution still valid, but here’s a more efficient way to get 14.
((10 + 5 + 7*3)^.5 + 5*2)^.5 + 5*2=14
Multiplication is shown for simplicity but can be accomplished using addition only. Highest number displayed is 36
The last math puzzle (beer jugs) also used fives and sevens as the only valid inputs. Coincidence??

What, nobody's going to try the negative root?
√ 5+5+5+5+5= -5
+7= 2
+7+7= 16
√ 16 =-4
+7+7= 10
+5+5+5= 25
√25= -5
+5+7+7= 14
√ 5+5+5+5+5= -5
+7= 2
+7+7= 16
√ 16 =-4
+7+7= 10
+5+5+5= 25
√25= -5
+5+7+7= 14

The problem says you’re using a calculator. Show me a calculator that gives a negative value for a square root.
Also, how does √ 5+5+5+5+5= -5 ?

The ASCII radical sign available here, that's just how it looks, no way to extend it over the whole statement. I suppose I should have used parentheses.
And I'll show you a calculator that gives a negative square root when you show me one that can only add 5 and add 7 and take square roots! This is a very unusual calculator to begin with, and unless stipulated we can make no assumptions about which square root.

All submitted answers look correct. Well done group!
I got this one from one of my puzzle videos from the Ted-Ed YouTube channel. This one is titled, "Can you solve the giant cat army riddle? - Dan Finkel"
