Simplify the radical expression. \( \sqrt[4]{\frac{2}{625}} \) Need Help? Readit

Question simplify \( \sqrt[3]{-128} \). Express the answer using a positive radicand.

For the following function, find the value of \( (a) f(-5) \) and (b) \( f(4) \), if possible. \( y=\left\{\begin{array}{l}x^{2}-4 \text { if } x \leq 0 \\ x^{3}+4 \text { if } x>0\end{array}\right. \) A. \( f(-5)=\square \) (Simplify your a a \( [ \) (aswer.) B. There is no solution.

\( 1 \leftarrow \quad \begin{array}{l}\text { Write the first four terms of the recursive sequence. } \\ a_{1}=6, a_{n}=5-a_{n-1} \text { for } n \geq 2\end{array} \) \( a_{1}=\square \) (Type an integer or a simplified fraction.)
