Ответ:
- \((2-x)^5=32-80x+80x^2-40x^3+10x^4-x^5\).
- \((x-2)^4=x^4-8x^3+24x^2-32x+16\).
- \((a+3)^4=a^4+12a^3+54a^2+108a+81\).
- \((3+a)^5=a^5+15a^4+90a^3+270a^2+405a+243\).
- \((x-1)^3=x^3-3x^2+3x-1\).
- \((1-x)^7=1-7x+21x^2-35x^3+35x^4-21x^5+7x^6-x^7\).
- \((x+1/x)^6=x^6+6x^4+15x^2+20+15/x^2+6/x^4+1/x^6\).
- \((2a+1/2)^6=64a^6+96a^5+60a^4+20a^3+15a^2/2+3a/2+1/64\).
