______x_______=56
So, this could be,
1x56
56x1
2x28
28x2
4x14
14x4
7x8
8x7
Hope this helps :)
I think Guest (the one who asked the question) means ___ * ___ = 56. I believe he means that the same number times itself is 56.
If that is so, then we can set the blank as a variable "x". x * x = 56. The star means "times/multiply". \(x^2 = 56\). Square root both sides, you get "blank" \( = \pm 2\sqrt{14}\).
