Solution

• $2+2+2=6$
• $3\times 3-3=6$
• $\sqrt{4} +\sqrt{4} +\sqrt{4} =6$
• $5+5\div5=6$
• $6+6-6=6$
• $7-7\div 7=6$
• $8-\sqrt{ \sqrt{8+8} }=6$
• $\sqrt{9\times 9} -\sqrt{9}=6$

Other solutions

• $2^{2}+2=6$
• $3!\times 3\div 3=6$
• $4\sqrt{4} -\sqrt{4} =6$
• $\sqrt[3]{8} +\sqrt[3]{8} +\sqrt[3]{8} =6$
• $(\sqrt[3]{8} )!+8-8=6$

Answer 2

Required Answer :-

So lets solve the question step by step

2 + 2 + 2 = 6

3 × 3 - 3 = 6

4√4 - 4 = 6

5 + 5 ÷ 5 = 6

6 + 6 - 6 = 6

7 - 7 ÷ 7 = 6

8 - √(√8 + 8) = 6

√(9 × 9) - √9 = 6

Let's check

3 × 3 - 3 = 6

9 - 3 = 6

6 = 6

4√4 - √4 = 6

4 × 2 - 2 = 6

8 - 2 = 6

6 = 6

5 + 5 ÷ 5 =6

5 + 1 = 6

6 = 6

7 - 7 ÷ 7 = 6

7 - 1 = 6

6 = 6

8 - √(√8 + 8) = 6

8 - √(√16) = 6

8 - 2 = 6

6 = 6

√9 × 9 - √9 = 6

√81 - √9 = 6

9 - 3 = 6

6 = 6
