I know of two ways of solving this  one requires the use of trig functions but the other one does not...

you are not allowed to use the number 3. the only "number" you can use are 2 and 2  i.e. two 2's

do u have to use both of the 2s?
 2 years ago

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

what r floor and ceiling functions?

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

floor basically says "drop the decimal part"

factorial and sqrt?
 2 years ago

asnaseerBest ResponseYou've already chosen the best response.0
it has sqrt and powers in it...

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

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

I gave you a clue already: it has sqrt and powers in it...

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

asnaseerBest ResponseYou've already chosen the best response.0
correct  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.

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