g.

rewrite in order

(45x²y²z² + 36x²y²z² + 18x²y²z²)  ÷  9xyz

99x²y²z² ÷ 9xyz  = 11xyz


h.

2xy (xy - 1) x       1         = xy - 1              (-2x²y² + 4x²y² = 2x²y²)

                       2xy


i)

{ (-2)⁴ x²z³y  + 2⁴z²x⁴ - 4z⁴y⁴}  ÷   2z²

= { 16x²z³y  + 16z²x⁴ - 4z⁴y⁴}  ÷   2z²

= 2z² (8x²zy + 8x⁴ - 2z²y⁴)  x     1    

                                                   2z²


= 8x²zy + 8x⁴ - 2z²y⁴    or   2³x²zy + 2³x⁴ - 2z²y⁴
