Quyidagi keltirilgan ko‘phadning qiymatini \(a = -2\) bo‘lganda hisoblab ekranga chiqaradigan dastur tuzing. $$\left(-5\right) \cdot {a}^{4} + \left(-40\right) \cdot {a}^{4} + \left(-5\right) \cdot {a}^{4} + \left(-15\right) \cdot {a}^{4}$$
Imkon qadar o‘zgaruvchi e’lon qilib, ifodani dasturning o‘ziga hisoblating.
