23. Esporre \( = \) II discorso di Telemaco contiene una considerazione sulla vita umana e sul destino: esponi gli argomenti di questa riflessione in un testo di circa 8 righe.

Write the expression with positive exponents only. Then simplify, if possible. \( \frac{x^{-5}}{y^{-1}} \) \( \frac{x^{-5}}{y^{-1}}=\square \)

Divide. \[ \frac{14 x^{2}-3 x-5}{5 x+10} \div \frac{49 x^{2}-25}{x+2} \] Simplify your answer as much

Tessa has \( t \) times as many comic books as Joseph. Joseph has 14 comic books. Write an expression that shows how many comic books Tessa has.

Solve for \( w \) \( \frac{w}{2}+2=4.97 \) \( w=\square \)

\( y ^ { \prime \prime \prime } + 2 y ^ { \prime } + y = e ^ { - t } \ln t \)
