a) ($x^{4}$ - 2x²+5xy) : (-x)
=(-x)³+2x-5y
b) (4xy²-2xy²z+3x²y) : 2xy
= 2y - yz + $\frac{3}{2}$ x
c) ( $x^{4}$$y^{3}$ - $\frac{1}{2}$ x³y³- x²y²) : $\frac{1}{5}$x²y²
=5x²y - $\frac{5}{2}$xy - 5
d) ( 5x²y - 2xy +3xy³) : (-2xy)
=-$\frac{5}{2}$x + 1 - $\frac{3}{2}$ y²
e) $( -$x^{4}$y³) ^{5}$ : ( -$x^{4}$y³)³
= ( -$x^{4}$y³)²
g) ( x+y - 3z)² : (x+y - 3z)
= x+y - 3z
