x^{\frac{2}{3}} (x^{2} - 4) = x^{\frac{2}{3}} x^{2} - x^{\frac{2}{3}} \cdot 4

= x^{\frac{2}{3}} x^{2} - x^{\frac{2}{3}} \cdot 4

x^{\frac{2}{3}} x^{2}

פשט את:

x^{\frac{8}{3}}

= x^{\frac{8}{3}} - x^{\frac{2}{3}} \cdot 4

\frac{5}{( x - 1 ) ( x + 4 )}

\frac{x ( 3 x ^{2} + 5 x + 3 )}{x + 1}

e^{k t} (5 - b t + 4 sin (\frac{t}{a}))

(2 x y - sec^{2} (x)) d x + (x^{2} + 2 y) d y

(2 - 2 cos (x))^{2}
