1(-3)^2*(-5/12)^2 eching

$$1 ( - 3 ) ^ { 2 } \times ( \frac { - 5 } { 12 } ) ^ { 2 }$$

Baholash

$$\frac{25}{16}=1,5625$$

Yechim qadamlari

2 daraja ko‘rsatkichini -3 ga hisoblang va 9 ni qiymatni oling.

$$1\times 9\times \left(\frac{-5}{12}\right)^{2}$$

9 hosil qilish uchun 1 va 9 ni ko'paytirish.

$$9\times \left(\frac{-5}{12}\right)^{2}$$

\frac{-5}{12} kasri manfiy belgini olib tashlash bilan -\frac{5}{12} sifatida qayta yozilishi mumkin.

$$9\left(-\frac{5}{12}\right)^{2}$$

2 daraja ko‘rsatkichini -\frac{5}{12} ga hisoblang va \frac{25}{144} ni qiymatni oling.

$$9\times \frac{25}{144}$$

\frac{25}{16} hosil qilish uchun 9 va \frac{25}{144} ni ko'paytirish.

$$\frac{25}{16}$$

Omil

$$\frac{5 ^ {2}}{2 ^ {4}} = 1\frac{9}{16} = 1,5625$$
