5. Find the slope of the line between the two points of \( (5,8)(7,14) \) \( \begin{array}{ll}\text { a. } 3 & \text { c. } 2 \\ \text { b. } 4 & \text { d. } 5\end{array} \)

จงพิสูจน์ว่าให้ a เป็นจำนวนเต็ม ถ้า a เปำนวนคู่ หรือ a เป็นจำนวนคี่ แล้ว \( \mathrm{a}+\mathrm{a} \) เป็นจำนวนคู่

23. (EPCAR 1990) Considere a expressāo \( 0,363636 \ldots+\frac{\frac{1}{3} \cdot 0,6-0,3}{\left(-\frac{1}{2}\right)^{3} \div \frac{3}{8}} \) seu valor é: a) \( \frac{7}{110} \) b) \( \frac{73}{110} \) c) \( \frac{109}{330} \) d) \( \frac{131}{330} \) e) \( \frac{109}{110} \)

Use radical notation to write the expression. Simplify if possible. \( -64^{\frac{1}{6}} \) Select the correct choice below and, if necessary, fill in the answer box to complete your choice. A. \( -64^{\frac{1}{6}}=\square \) (Type an exact answer, using radicals as needed. Simplify your answer.)
