Simplify. Enter the result as a single logarithm with a coefficient of 1 . To enter the \( \log \), click in the answer cell, then click on the small yellow arrow on the right. Then click the Functions tab to access the log. If needed, you can change the base. Using the keyboard, you can also enter \( \log _{3}\left(5 x^{4}\right) \) as \( \log _{3} 3\left(5 x^{\wedge} 4\right) \). \( \log _{2}\left(8 x^{3}\right)+\log _{2}\left(2 x^{9}\right) \) \( = \)

N) \( 2^{3} \cdot 2^{3} \) b) \( 2^{50}: 2^{47} \)

Solve for \( x \) if \( x=\sqrt{x+\sqrt{x+\sqrt{x+\sqrt{x+\sqrt{x+\ldots}}}}} \)

\begin{tabular}{l} 25. \begin{tabular}{l}\( -6 x+4 y \geq 8 \) \\ \( y<-x-1 \) \\ \begin{tabular}{|l|l|l|l|}\hline \\ \hline & \\ \hline\end{tabular} \\ \hline \\ \hline\end{tabular} \\ \hline\end{tabular}

Pedro y Juan tienen entre ambos \( \$ 45.000 \). Si Pedro tiene el triple de Juan. ¿Cuánto dinero tiene Juan?

3. Mathon went to Inkhorn Bookstore where he got a discount of P15 from a book that was marked \( 20 \% \) off. Then, he went to Lofty Bookstore to check out one of their limited edition books that is now discounted at \( 30 \% \). If Mathon got a discount on the book from the Lofty Bookstore for the same amount as the original price of the book he got from Inkhorn Bookstore, how much is the difference between the two books' original prices?
