Ifodani hisoblang.

$$S = \displaystyle\sum_{a=1}^{x}\frac{a^2+2a}{a^3+acos^2a+1}$$

$$P = \prod_{i = 1}^{y}\frac{i^2+1}{\sqrt[i] {i^3} + 2}$$

$$SP = \displaystyle\sum_{i=1}^{a} \prod_{k = 1}^{b} ln\frac{k^i+\sqrt[i]{k}}{k^3+\sqrt[k]{i}}$$

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

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