fill in the missing signs to make the sum correct...........8 ? 4 ? 4=9

Answer 1

if the signs do not need to be limited to those indicating addition, subtraction, multiplication and division:

8^0 + 4 + 4 = 9

8^0 = 8 to the zero power = 1

Or it could be:

8 + 4/4 = 9

I hope this helps. Thanks for asking.
