1) \( x-3<-4 \)

26. Simplifica y expresa el resultado con exponente positivo. \( \begin{array}{llll}\text { a) } \frac{x^{\frac{1}{3}}}{x^{\frac{2}{3}}} & \text { b) }\left(a^{-\frac{1}{2}}\right)^{-6} & \text { c) } x^{\frac{1}{4}} x^{-\frac{3}{4}} & \text { d) }\left(x^{4} y^{6}\right)^{-\frac{1}{2}}\end{array} \)

simplify it \( \sqrt[4]{r^{3} s \sqrt[5]{r^{2} \cdot s^{4}}} \div \sqrt{r^{2} s^{2}} \)

What does the exponent in an expression indicate?

Aggiungi al prodotto tra 2 e \( \frac{1}{3} \) la differenza tra 1 e \( \frac{1}{2} \) dividila somma ottenuta per 12 . \( (x) \)

Simplify it \( \sqrt[4]{r^{3} s \sqrt[5]{r^{2} \cdot s^{4}}} \div \sqrt{r^{2} s^{2}} \)
