Baham ko'rish
Klipbordga nusxa olish
-1-\frac{\left(-\frac{1}{4}\right)^{-2}}{-4}
-1 daraja ko‘rsatkichini -1 ga hisoblang va -1 ni qiymatni oling.
-1-\frac{16}{-4}
-2 daraja ko‘rsatkichini -\frac{1}{4} ga hisoblang va 16 ni qiymatni oling.
-1-\left(-4\right)
-4 ni olish uchun 16 ni -4 ga bo‘ling.
-1+4
-4 ning teskarisi 4 ga teng.
3
3 olish uchun -1 va 4'ni qo'shing.
