(x^ two +(nine *y^ two)/ four +z^ two - one)^ three -(x^ two)*(z^ three)-(nine *(y^ two)*(z^ three))/ eighty = zero
(x squared plus (9 multiply by y squared ) divide by 4 plus z squared minus 1) cubed minus (x squared ) multiply by (z cubed ) minus (9 multiply by (y squared ) multiply by (z cubed )) divide by 80 equally 0
(x to the power of two plus (nine multiply by y to the power of two) divide by four plus z to the power of two minus one) to the power of three minus (x to the power of two) multiply by (z to the power of three) minus (nine multiply by (y to the power of two) multiply by (z to the power of three)) divide by eighty equally zero
(x2+(9*y2)/4+z2-1)3-(x2)*(z3)-(9*(y2)*(z3))/80=0
x2+9*y2/4+z2-13-x2*z3-9*y2*z3/80=0
(x²+(9*y²)/4+z²-1)³-(x²)*(z³)-(9*(y²)*(z³))/80=0
(x to the power of 2+(9*y to the power of 2)/4+z to the power of 2-1) to the power of 3-(x to the power of 2)*(z to the power of 3)-(9*(y to the power of 2)*(z to the power of 3))/80=0
