Ifodani hisoblang.

$$S = \displaystyle\sum_{k=1}^{x}\frac{(-1)^k(k+1)}{k^3+k^2+1}$$

$$P = \prod_{i = 1}^{y}\frac{i^3+|i-9|}{ln(i)+7i}$$

$$SP = \prod_{n = 1}^{c}\displaystyle\sum_{m=1}^{d}(-1)^m\frac{ln(m+5)}{m^{n+3}+nm}$$

Kiruvchi ma’lumotlar: Bitta satrda $x,y,c,d$ butun sonlar ($1\le x,y,c,d \le 10$);

Chiquvchi ma’lumotlar: Bitta satrda probel bilan ajratilgan xolda $S,P,SP$ – masala yechimlari. javoblar $10^{-2}$ aniqlikda chiqarilsin.
