1) -4m²n·(-0.6m³n⁴)
2) (a⁻⁴)⁸:a⁻¹⁶
3) (-m⁻⁵n⁻⁴)⁸·4m⁻⁴n¹⁶

Answer 1

$-4m^2n*(-0,6m^3n^4)=2,4m^5n^5\\\\(a^{-4})^8:a^{-16}=a^{-16}\\\\(-m^{-5}n^{-4})^8*4m^{-4}n^{16}=-4m^{-44}n^{-16}$

Answer 2

1)-4*(-0,6)m^(2+3)*n^(1+4)=2,4m^5*n^5
2)a^(-32):a^(-16)=a^(-32+16)=a^(-16)
3)-m^(-40)*n^(-32)*4m^(-4)*n^16=4m^(-40-4)*n^(-32+16)=4m^(-44)*n^(-16)
