Задание 365

$\frac{x^{3,28}\cdot4(y^{1,15})^5}{x^{1,63}}:\frac{x^4y^{-0,25}}{x^{2,35}\cdot y^{-6}}=$$4x^{3,28-1,63}\cdot y^{5,75}\cdot \frac{x^{2,35}\cdot y^{-6}}{x^4\cdot y^{-0,25}}=$$4\cdot \frac{x^{1,65+2,35}\cdot y^{5,75-6}}{x^4\cdot y^{-0,25}}=$$4\cdot \frac{x^4\cdot y^{-0,25}}{x^4\cdot y^{-0,25}}=4\cdot 1=4$
