Puzzle 86 - solution

-

 Puzzle 86 was 

Using only 3 nines and any of the operators +,-,X ,/ and √, can you get the numbers 1, 4 and 6?


Solution:

The original question in reddit says there are multiple answers. I copied (wink-wink) only one answer.

1 = √(9X9)  / 9

4 = √9 + 9/9

6 =  √(9X9) - √9

Puzzle 66 - solution

 The question was  What is wrong with this proof ? a=b multiply both the sides by a     --1 a2 = ab  add -b2 to both the side           --2 a2-b2 =ab-b2  factorizing                                --3 (a+b)(a-b) = b(a-b)  divide both the sides by (a-b)    ---4 a+b=b Substituting a with b,              ---5 2b = b Dividing both the sides by b    ---6 2 = 1   The problem is with step 4. When a is equal to b, a-b is zero. You can not divide numbers by zero because division is only defined for non-zero numbers.
