22. What is the simplified form of the expression \( \log (8)+\log (2) \) ? A. \( \log (10) \) B. \( \log (16) \) C. \( \log (18) \) D. \( \log (20) \)

Question Simplify: \( \sqrt{9+16} \) (Enter \( \varnothing \) if your answer is not a real number.)

Question simplify: \( \sqrt[6]{x^{18}} \)

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.

Question simplify: \( \sqrt{\frac{294}{6}} \)

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