при возведении степени в степень показатели перемножаются. при умножении степеней с одинаковыми основаниями показатели складываются, а при делении вычитаются.

в третьем 15/15=1

1. 2(с³)²*(х⁸)³/(5*(с²)⁵(х⁴)³)=2*с⁶х²⁴/(5с¹⁰х¹²)=2х¹²/(5с⁴)

2. а⁸*а⁵:а³/(а¹⁰:а⁶*а²)=(а⁸⁺⁵⁻³)/(а¹⁰⁻⁶⁺²)=а¹⁰/а⁶=а¹⁰⁻⁶=а⁴

3. 15а¹³*х²/((3а⁶*х²)*(5а⁴))=а¹³⁻⁶⁻⁴=а³
