-1/27

There are two important thing in this quesion which can create problem for us. One is exponent is negative. And second is what is base under the exponent 3 or -3.

The solution of these two confusions is as following

1-I already mention in negative exponent related articles that first convert the negative exponent into positive exponent.

2-I have also explained that the base with a negative sign without paratheses mean exponent is not on negative sign.

-3 -3 1 = ---- 3 -3 1 = ------- 3 -1.3 1 = ----- -27 1 = - ---- 27
