Directions: Using the digits 0 to 9, at most one time each, fill in the boxes to make a result that is as close to zero as possible.

### Hint

What happens when you have a negative exponent?

Where does the 1 go?

Where does the 1 go?

### Answer

8 ^ (-2) = 1 / 64

How can you use the 4 in two places in the equation? If that’s allowed, then 2 ^ -6 = 1/64 should also be allowed.

Or 9^-2 = 1/81

or 3^-4 = 1/81

you use 1 twice bud

Good spot Ms. M. I have removed that solution.

So, it seems 7^-2 = 1/49 and 8^-2 = 1/64 are the only solutions which use unique digits, with the latter being closer to zero.

Any two-digit number at power -1

32^(-1) = 1/32

26^(-1) = 1/26
