Question

HEEELLLPPP!!!!!!!!! PLEEAASEEE!!!!!!!!

Answer 1

Explanation:

`17. (a^(m))^(n)=a^(m*n)\\\\a^(m)*a^(n)=a^(m+n)\\\\-3k^(2)*(4k^(5))^(3)=-3k^(2)*4^(3)*k^(5*3)\\\\ = -3k^(2)*64*k^(15)\\\\= (-3)*64*k^(2+15)\\\\= - 192k^(17)`

`19. (a^(m))/(a^(n))=a^(m-n)\\\\\\((-7p^(4))*(-8p^(5)))/(2p^(3))= ((-7)*(-8)*p^(4)*p^(5))/(2p^(3))\\\\\\=(-7)*(-4)*p^(4+5-3) \\\\= 28p^(6)\\`

`20)(15a^(16)b^(11))/((3a^(4)b^(2))^(3))=(15a^(16)b^(11))/(3^(3)*a^(4*3)*b^(2*3))\\\\\\=(15a^(16)b^(11))/(27*a^(12)*b^(6))\\\\=(5*a^(16-12)*b^(11-6))/(9)\\\\\\=(5a^(4)b^(5))/(9)`
