Question

How do you simplify `-(2/3)^4`?

Answer 1

`-(2/3)^4` `=` `-16/81`

Explanation:

`-(2/3)^4` `=` `-1xx(2/3)^4` `=` `-1xx2^4/3^4` `=` `-1xx16/81=-16/81`.

Had the problem been written `(-2/3)^4`, the the answer would be `16/81`, but the brackets and the normal order of algebraic operations dictate a NEGATIVE answer.
