Answer 2

Are you missing a sign?

Answer 3

Hi,

7 - 3 = 4.

I feel you are missing a sign, as @pabloecortez07 stated.

Answer 4

7-^3

Answer 5

Hi,

\[7^-3 = -7 * -7 * -7 = -343\] Remember, you cannot have a negative number. Therefore, by putting it over one, we can make it positive. \[\frac{ 1 }{ 343 }\]

Thank you for letting me help you! :)

Answer 6

I guess you can do that but, normally 7^-3 is 1/7^3

So, 7 * 7 * 7 = 343

1/343 :P
