This square root "trick" is going viral. It works for 25, 196, 64 and 289... 🤔
Can you find a number that BUSTS it? 👇

☄️ The meteor has landed: 3.5π ≈ 11 m²! ¾ of a 2 m circle (3π), plus the rope wraps around 2 corners for two ¼ circles of 1 m (π/2) 🐑

☄️ The meteor has landed: 4 + 0 = 4! Take the middle match from the 8 and turn − into +.
Bonus 2nd answer 4 = 8 − 4, found by @5900Eric 🎯
10
☄️ The meteor has landed: 23! Only the 4 gets multiplied by 0, so 20 − 0 + 3 = 23.

BUSTED #2, idea by @5900Eric 🎲 This cube root "trick" works for 125, 216 and 343... but fails at 512. Only 3 more cubes in existence pass. Can you find them? 👇
☄️ The meteor has landed: 2744, 3375 and 4096 (∛ = 14, 15, 16). 2+7+4+4−3 = 14 ✅
After that, it never works again. Busted! 💥

☄️ The meteor has landed: 13!
Put the center at 0: the corners (−12, 5) and (5, 12) are both 13 away. A hidden 5-12-13 triangle, twice 😏
