Evaluate the value of expressions.
[tex]\begin{gathered} -(\frac{1}{3})^4=-\frac{1\cdot1\cdot1\cdot1}{3\cdot3\cdot3\cdot3} \\ =-\frac{1}{81} \end{gathered}[/tex]
So answer is -1/81.
Simplify the expression.
[tex]\begin{gathered} (-\frac{5}{3})^2=\frac{-5}{3}\cdot\frac{-5}{3} \\ =\frac{25}{9} \end{gathered}[/tex]
So answer is 25/9.
