Question

Given below is a very interesting maths problem.
This was set out by a German. It is a little difficult and can help prevent Alzheimer disease.

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

Use any of mathematical signs wherever you need.


Go ahead and get your mind busy .

Answer 1

Answer:

I like puzzles that can have different solutions depending how you look at them. I always get a different perspective from the GeekDad readers. This weeks puzzle was to make these equations correct by using mathematical operations.

1 1 1 = 6

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

10 10 10 = 6

One quick way is to use the fact that (3)! is equal to 6. So to take the easy route you could just add each number raised to the 0 power and take the factorial:

(n^0 + n^0 + n^0)!

(1 + 1 + 1)!

(3)!

That is the quick way and some of you went with that. The adventurous ones out there had a different answer for each one. Here are some of the popular ones.

(1+ 1+ 1)! = 1*2*3 = 6

2 + 2 + 2 = 6

3 * 3 - 3 = 6

4 + 4 - sqrt(4) = 6

5 + 5/5 = 6

6 * 6/6 = 6

7 - 7/7 = 6

cubroot(8) + cuberoot(8) + cuberoot(8) = 2 + 2+ 2 = 6

(9 + 9) /sqrt(9) = 6

log((10 *10 * 10)^2) = log((1,000)^2) = log(1,000,000)= 6

Of course everyone knows there are 10 types of people, those who understand binary and those who don't. A number of the readers certainly understand binary by taking 10 10 10 to be binary representations of 2 2 2 and adding. Very out of the box thinking !

2+2+2=6  

2×2+2  = 6

3×3-3=6

√3×√3+3 = 6

√4+√4+√4=6

4 + 4 ÷ √4 = 6

√4×√4 + 4 = 6

5÷ 5 +5 = 6

6+ 6-6 = 6

6 ×6÷ 6 = 6

7 - 7÷ 7 = 6

[√7] + [√7] + [√7] = 6

√7 × √7 - [∛7] = 6

∛8 + ∛8+ ∛8 = 6

[√8] + [√8] + [√8] = 6

√9×√9-√9=6

9 - 9 ÷√9=6
