Answer 1

4) $frac{2x ^{6} }{6} left { {{1} atop {-1}} right. = frac{x^{6}}{3} left { {{1} atop {-1}} right. = frac{1}{3}- frac{1}{3}=0$

$- frac{1}{x} - x^{3} left { {{4} atop {2}} right. } = -frac{1}{4}-64+ frac{1}{2}+8=-0,25-56+0,5 =-55,25$

5) $intlimits^3_1 { (x^{2} +4x+5)} , dx = frac{ x^{3} }{3}+2 x^{2} +5x left { {{3} atop {1}} right. =9+18+15- frac{1}{3}-2-5=$35-1/3=$34 frac{2}{3}$
