Calcola. a) \( 2^{2000} \cdot 0,5^{2000} \) b) \( 4^{503} \cdot 0,25^{501} \) c) \( 4^{3000} \cdot 4^{100} \cdot 0,25^{3101} \) d) \( 6^{503} \cdot\left(\frac{1}{6}\right)^{501} \)

Solve for \( x \) \[ y-\frac{5}{x}=\frac{3}{v} \]

\( x^{4}-9 x^{2}+3+x \) entre \( x+3 \)

Solving Systems of Equations Exit Ticket 1. Mindy's high school class has a total of 150 students and they are planning a field trip. The school has smal buses and vans to transport all students. Each van can seat 8 students and each bus can seat 14 students. Ther are only 15 drivers, so the total number of vehicles that they can take must be 15 . How many of each vehicle will Mindy's class need to transport everyone?

\( x^{3}-y^{3} \) entre \( x-y \).

\( a^{3}+3 a b^{2}-3 a^{2} b-b^{3} \) entre \( a-b \)
