Aplica la propiedad del cociente de potencias a esta expresión: \( \frac{y^{5}}{y^{-2}} \).

For the graph of the function \( f(x) = 5^{x-1} - 2 \), what are the coordinates of the y-intercept?

Evaluente: \( (64)^{6 / 5} \div(64)^{1 / 5} \)

26. The diagonal of a rectangular field is 20 m more than the shorter side of \( i t \). If the shorter side is 10 m less than the longer side, then find the sides of the rectangular field.

5. Sivetai \( \eta \) пapáotaoŋ \( : ~ A=\frac{x^{2}-4 x y+4 y^{2}}{15} \cdot \frac{9}{x^{2}-4 y^{2}} \) а) Na апобгіंदॄтв о̀тı: \( A=\frac{3 x-6 y}{5 x+10 y} \). i) \( \frac{x}{y} \) ii) \( \frac{3 x+2 y}{x-y} \)
