Default Re: Use four 0's & any mathematical operators to get 24

Rather difficult
But let me give it a shot

cos-1 (inverse) 0 = 90
√90 = 9.5
and 3√90 = 4.5
√cos (inverse) 0 + √cos (inverse) 0 + √cos (inverse) 0 -3√cos (inverse) 0
= √90 + √90 + √90 - 3√90
= 9.48 +9.48 + 9.48 – 4.48
= 28.44 – 4.48
= 23.9

after taking square root and cube root if we approximate

that is

9.5 + 9.5 + 9.5 – 4.5
then answer is exactly 24

How about it Biggie
