[(4! + √4)/.4] + 4! = [(24 + 2)/.4] + 24 = 26/.4 + 24 = 65 + 24 = 89
89 = 88 + (8 / 8)
With a bit of a cheat: 88 + 8/8 = 89
88 + 8/8 = 88 +1 = 89
The fact family for 89 and 72 consists of the numbers 89, 72, and their sum, which is 161. The related addition and subtraction equations are: 89 + 72 = 161 and 161 - 89 = 72, as well as 161 - 72 = 89. Thus, the fact family includes these four equations.

To create the number 89 using the digit 8 four times, you can express it as 88 + 8/8. This translates to 88 + 1, which equals 89.
88 + 8/8 = 89
88 + 8/8 = 88 +1 = 89
89 = 88 + (8 / 8)
With a bit of a cheat: 88 + 8/8 = 89
