при возведении степени в степень показатели умножайте. поэтому ответы

1)а¹²

2)а²⁰, учли, что минус один в четной степени равно плюс один, и что степень произведения равна произведению степеней.

4)а³⁰

при умножении степеней с одинаковыми основаниями показатели складываются, при делении вычитаются, поэтому ответы на

3) х⁸

5)а³⁰*а²⁰=а⁵⁰

6)-а⁴²*(-а⁹)/а¹⁵=а³⁶

здесь учли, что минус один в нечетной степени равно минус один.

7)а²⁴*а¹³/а¹⁶=а²¹

Пошаговое объяснение:

(а⁶)² = а⁶*² = а¹²

(-а⁵)⁴ = (а⁵)⁴ = а⁵*⁴ = а²

х³х⁵ = х³+⁵ = х⁸

((а³)²)⁵ = (а³*²)⁵ = (а⁶)⁵ = а⁶*⁵ = а³

(а¹⁰)³ * (а⁵)⁴ = а¹⁰*³ * а⁵*⁴ = а³⁰ * а²⁰ = а³⁰+²⁰ = а⁵

(-а⁶)⁷ * (-а³)³ : а¹⁵ = -а⁶*⁷ * (-а³*³) : а¹⁵ = -а⁴² * (-а⁹) : а¹⁵ =

а⁴² * а⁹ : а¹⁵ = а⁴²+⁹ : а¹⁵ = а⁵¹ : а¹⁵ = а⁵¹-¹⁵ = а³

а²⁴ : (а⁸)² * а¹³ = а²⁴ : а¹⁶ * а¹³ = а²⁴-¹⁶ * а¹³ = а⁸ * а¹³ = а⁸+¹³ = а²¹
