2. Nilai \( x \) yang memenuhi persamaan \( 4^{x+3}=\sqrt[3]{8^{x}} \) adalah \( \ldots \) \( \begin{array}{ll}\text { A. } 6 & \text { D. }-3 \\ \text { B. } 3 & \text { E. }-6 \\ \text { C. } \frac{18}{5} & \end{array} \)

Solve. Separate your answers with a comma, and please write fractions in reduced form, no decimals. \( 8|4 x-9|=16 \)

Perform the indicated operation \& simplify. Express the answer in terms of \( i \) (as a complex number). \( (-9+11 i)^{2}=\square \)

8. \( 3^{3} \div 3+3-3(3) \)

48) \( -1,3,-2 \) A) \( f(x)=x^{3}-6 x^{2}-7 x-6 \) B) \( f(x)=x^{3}+2 x^{2}-7 x-6 \) C) \( f(x)=x^{3}-7 x-6 \) D) \( f(x)=x^{3}-6 \)

Factor. Then find all zeros. \( \begin{array}{l}\text { 46) } f(x)=x^{3}-2 x^{2}-8 x \\ \text { A) }\{0,-2 \text { mult. } 2\} \\ \text { B) }\{0,-2,4\} \\ \text { C) }\{0,-2,-5\} \\ \text { D) }\{0 \text { mult. } 2,4\}\end{array} \)
