Answer 1

(ii) 8x(cube) + 27y(cube) + 36x(square)y + 54y(square)x

= (2x)cube + (3y)cube + 3 × (2x)square × 3y + 3 × 2x × 3y(square)

= (2x+3y)cube

(iii) x(cube) - 8y(cube) - 125z(cube) - 30xyz

= (cuberoot x)cube - (2y)cube - (5z)cube - 30xyz

= (cuberoot x + 2y + 5z){[cuberoot x]square + 4y(square) + (5z) square - 2(cuberoot)xy - 10yz - 5z(cuberoot)x}
