Answer 1

Ответ:

1) (y^4)^3=y^12

2) (-x^6)^2=-x^12

3) m^5m^4=m^5+4=m^9

4) ((a^7)^3)^2=a^42

5) a^6 • (a^2)^4=a^6 a^8=a^14

6) (-a^5)^3 • (-a^4)^7=-a^15•(-a^28)=a^43

Answer 2

$\displaystyle 1)(y^4)^3=y^4^*^3=y^1^2\\\\ 2)(-x^6)^2=(x^6)^2=x^1^2\\\\ 3)m^5m^4=m^5^+^4=m^9\\\\ 4)((a^7)^3)^2=(a^2^1)^2=a^4^2\\\\ 5)a^6(a^2)^4=a^6*a^8=a^1^4\\\\ 6)(-a^5)^3(-a^4)^7=-(a^5)^3*(-(a^4)^7)=a^1^5*a^2^8=a^4^3$
