x = √20 + √20 + √20.......∞ // x = √20 - √20 - √20.......∞ // x = √20 * √20 * √20.......∞ // x = √64 ÷ 64 ÷ √64......∞
x = √30 + √30 + √30...... ∞ // x = √30 - √30 - √30....... ∞ // x = √30 * √30 * √30.......∞ : Click Here
Trick:
- Inside number = 20
- 20 = 4 × 5
If "+" sign, answer = big number = 5
If "−" sign, answer = small number = 4
If "x" sign, answer = The number = 15
If "÷" sign, answer = The number = ∛27
Remember: “+” means “big”, “−“ means “small”, " x" mean Same Number, "÷" means ∛Number
