Una sede de AlEP se ha visto afectada por un vinus alfamente contagioso. Cada enfermo contagia a tres personas al dia. Si el lunes hay una persona contagiada, ¿ cuántas personas serán contagladas al finalizar el sábado?

7. \( 3 \sqrt{2}+4 \sqrt{8}-5 \sqrt{50}+8 \sqrt{32} \)

Express \( x^{\frac{3}{4}} \) in terms of a radical expression.

Anastasia chooses a 4-digit number. The digits are all odd. The digits are all different. Her number rounds to 1500 when rounded to the nearest 100 Write the largest number that Anastasia could choose.

Rewrite the fraction in the sentence below as a percentage. In a certain class, \( \frac{21}{25} \) of the students got problem 5 wrong on Friday's math test. Percent notation: \( \square \% \)

Simplify: \( \frac{(6.25)^{\frac{1}{2}} \times(0.0144)^{\frac{1}{2}}+1}{(0.027)^{\frac{1}{3}} \times(81)^{\frac{1}{4}}} \)
