**Use four 0's & any mathematical operators to get 24**

For those who don't have to do anything better -

Use four 0's (zeros) and any mathematical operators to get 24.

Those who are smart, don't spoil the fun soon. Others, give it a try.

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

Also instead of cube root of 90 we can do

ln90 = 4.49

ln90 = 4.49

Hint -

K.I.S.S 😁

...and since when did we start relying on 'approximate' values?

On the same lines, I've another question -> is 0.999999...(infinite times) equal to 1 ?

If yes, how? If not, why? 😉

Yes, that's right. Only four zeros! (and of course, mathematical operators).

Is it really 'that' difficult?

Is it really 'that' difficult?

Nope, it is never equal to 1. Only 1 is equal to 1. In most practical uses it is close enough mathematically to round the .99999 to 1 however it is never actually equal to 1.

1. No, you cannot 'rotate' operators. Come on, its just basic mathematics!

2. If 0.99999...(infinite) is not equal to one, what's wrong with the following? -

x = 0.99999...(infinite times)

10x = 9.9999.......

=> 9x = 9

=> x = 1

😁

What say? 😉

Here is your problem, the tricky business between the 10x=9.999999... and then 9x=9. Did you change the value of x?

gohmHere is your problem, the tricky business between the 10x=9.999999... and then 9x=9. Did you change the value of x?

Umm, okay, here we go -

x = 0.99999...(infinite times) - Equation (A)

10x = 9.9999....... - Equation (B)

Equation (B) minus (A)

=> 9x = 9

=> x = 1

Hah, no problem with factorials! That's the right way to get 24. Pretty easy, eh? 😀mahulFour zeroes to score 24, that's easy-->>

(0!+0!+0!+0!)!=24

i hope that would do, unless _k has a problem with my repeated use of factorials 😀
