X^3+yx^2+yx^2+xy^2-xy^2-y^3=x^3+2yx^2-y^3
4a^2(b^2+16a^2*b^2)-20ab(0.2ab-1)(8a^2*b^2)^2=4a^2*b^2(1+16a^2)-20ab(0.2ab*64a^4*b^4-64a^4*b^4)=4a^2*b^2(1+16a^2)-20ab(12.8a^5*b^5-64a^4*b^4)=4a^2*b^2(1+16a^2)-20ab*12.8a^4*b^4(ab-5)=<span>4a^2*b^2(1+16a^2)-256a^5*b^5(ab-5)
Ответ:</span><span>4a^2*b^2(1+16a^2)-256a^5*b^5(ab-5)
Больше никак не упростить, только так</span>
X^2-x+9=x^2+4x+4
x^2-x+9-x^2-4x-4=0
-5x=-5
x=1
Решение
1) (x⁵ + 1)` = 5x⁴
2) (- 1/x - 3x)` = 1/x² - 3
3) (4x⁴ + √x) = 16x³ + 1/2√x
4) ((1/3) * x³ - 2√x + 5/x)` = x² - 1/√x - 5/x²
5) ((5x - 4)*(2x⁴ - 7x + 1))` = 5*<span>(2x⁴ - 7x + 1) + (5x - 4)*(8x</span>³ - 7)
6) [(x³ - 7)/(3 - 4x⁴)]` = [3x² * (3 - 4x⁴) + 16x³ * (x³ - 7)] / (3 - 4x⁴)²
