1 - x^6(x^-2,7 - x^-2,3)(x^-3,3 + x^-2,9 + x^-2,5)

Answer 1

1-x6(x^-2.7-x^-2.3)(x^-3.3+x^-2.9+x^-2.5) = 

= 1+(-x8+3.3x7-x8+2.9x7-x8+2.5x7+2.7x7-8.91x6+2.7x7-7.83x6+2.7x7-6.75x6+x8-3.3x7+x8-2.9x7+x8-2.5x7+2.3x7-7.59x6+2.3x7-6.67x6+2.3x7-5.75x6) = 

= 1-x8+3.3x7-x8+2.9x7-x8+2.5x7+2.7x7-8.91x6+2.7x7-7.83x6+2.7x7-6.75x6+x8-3.3x7+x8-2.9x7+x8-2.5x7+2.3x7-7.59x6+2.3x7-6.67x6+2.3x7-5.75x6 = 

= 15x7 – 43.5x6 + 1
