prosze tylko odpowiedziec czy dobrze zrobiłam zadanie ! :) kalina: W pierścieniu wielomianów C[x] obliczyć [(1+i)+x+(3−i)x²+(5+i)x³][(3+(5−i)x+(2+i)x²]+[7+(3−i)x+(4+i)x³]. a. (10+3i)+(12+3i)x+(15−i)x²+(35−3i)x³+(35+i)x⁴+(9+7i)x⁵ b. (10+3i)+(12+3i)x+(15−i)x²+(35−3i)x³+(36+i)x⁴+(9+7i)x⁵ c. (10+3i)+(12+3i)x+(15−i)x²+(35−3i)x³+(33+i)x⁴+(9+7i)x⁵ d. (10+3i)+(12+3i)x+(15−i)x²+(35−3i)x³+(34+i)x⁴+(9+7i)x⁵ tutaj mi wyszło d
