Solution: **C(56/8, 3) - 11 = C(7,3) - 11 = 35-11 =24 ?**

New numbers: **509 3 3 3**

Hmmm BTW you can’t use the GCF and LCM functions.

This one is a nice puzzler. 509 is prime, so likely something to do with exponents with such a large number. 24^2 = 576 and is close enough to it. Maybe factorials? IDK.

A hint please…?

sqrt[3][509+3] times 3 = 8 times 3.

BTW how do I make the multiplication sign without making it italicized?

This is one i can do. lol

56 x 34 = 1904 then you go 1904 - 1880 = 24
