You have two numbers, 9 and 20. Can you make 6?

You must use each of the two numbers exactly once.

You can use math operations: +, -, x, /, exponents, roots or factorials.

You can combine (concatenate) original numbers: e.g. 9 & 20 make 920 or 20 & 9 make 209

You cannot combine any numbers besides the original ones, split any number into separate digits,

turn numbers upside down, approximate, truncate, use summations or any math operations beyond the ones stipulated above.

Have fun!

((sqrt9)!)x(20^0)

would be allowed to do that. If you were anything less I would say you pulled a zero out of the air that doesn't exist. Welcome to the forum.

i got the answer.....

it is mod{(20/(sqrt(9))}

20 divided by 3 is 6.666 and it's mod would be 6........

I followed you to the 6.666...,

but not sure how you are meaning the use of the mod. Are you truncating maybe?

(My understanding of mod is that it is the remainder after a division -- e.g. 17 mod 5 = 2, since 17/5 gives a remainder of 2.)

ok..

don't take it as mod but....greatest integer less than the given no.
