Puzzle time: You are allowed to use any number of mathematical operators or functions (e.g. +, , *, /, sin, cos, tan, factorial, sqrt, etc) but only two constants both of which must be the number 2.

Best ResponseYou've already chosen the best response.0I know of two ways of solving this  one requires the use of trig functions but the other one does not...

Best ResponseYou've already chosen the best response.0you are not allowed to use the number 3. the only "number" you can use are 2 and 2  i.e. two 2's

Best ResponseYou've already chosen the best response.0do u have to use both of the 2s?

asnaseer

Best ResponseYou've already chosen the best response.0yes  the expression you end up with must have exactly two 2's within it

Best ResponseYou've already chosen the best response.0i though it needs to be equal to 2 my bad

karatechopper

Best ResponseYou've already chosen the best response.0can there be more 2s?

Best ResponseYou've already chosen the best response.0trying to use floor and ceiling functions was a clever thought though @moneybird

Best ResponseYou've already chosen the best response.0what r floor and ceiling functions?

asnaseer

Best ResponseYou've already chosen the best response.0floor(1.5678)=1 ceiling(1.5678)=2

asnaseer

Best ResponseYou've already chosen the best response.0can we more than just two 2s?

asnaseer

Best ResponseYou've already chosen the best response.0both answers that I have are /fairly/ simple  so no magical complicated functions are needed

karatechopper

Best ResponseYou've already chosen the best response.0is one of them with no trignometric functions in it?

Best ResponseYou've already chosen the best response.0ok..so it has like somple ones tht a third grader is familiar with?

Best ResponseYou've already chosen the best response.0factorial and sqrt?

asnaseer
 5 years ago
Best ResponseYou've already chosen the best response.0it has sqrt and powers in it...

karatechopper

Best ResponseYou've already chosen the best response.0if i use 2 as a power, does it still count as one of the 2s?

asnaseer

Best ResponseYou've already chosen the best response.0but the purer answer uses only trig functions

Best ResponseYou've already chosen the best response.0who said this was going to be easy? ;)

Best ResponseYou've already chosen the best response.0hmmm i need clues...

asnaseer

Best ResponseYou've already chosen the best response.0I gave you a clue already: it has sqrt and powers in it...

karatechopper

Best ResponseYou've already chosen the best response.0but u can have only two 2s! and if i say 2 to the power of 2 then my 2s r used!!!!

asnaseer

Best ResponseYou've already chosen the best response.0correct  so think of other ways of using sqrt and powers  and remember "power" does not mean it has to be to the power to "2". as long as the only digits that appear in the answer are two 2's  then the solution is valid.

karatechopper

Best ResponseYou've already chosen the best response.0so u mean they can be to the power of any number?

Best ResponseYou've already chosen the best response.0if I say anymore I will give the answer away :)
