Ikki eksponentning koʻpaytmasi uchun qadamlar

Ifodani qisqartirish uchun eksponent qoidalaridan foydalanish.

$$\left(-2a^{2}\right)^{1}\times \frac{1}{-a^{2}}$$

Ikki yoki undan ko'p raqam koʻpaytmasini daraja ko'rsatkichiga oshirish uchun har bir raqamni daraja ko'rsatkichiga oshiring va ularning koʻpaytmasini chiqaring.

$$\left(-2\right)^{1}\left(a^{2}\right)^{1}\left(-1\right)\times \frac{1}{a^{2}}$$

Ko'paytirishning kommutativ xususiyatidan foydalanish.

$$\left(-2\right)^{1}\left(-1\right)\left(a^{2}\right)^{1}\times \frac{1}{a^{2}}$$

Daraja ko‘rsatkichini boshqa ko‘rsatkichga oshirish uchun, darajalarini ko‘paytiring.

$$\left(-2\right)^{1}\left(-1\right)a^{2}a^{2\left(-1\right)}$$

2 ni -1 marotabaga ko'paytirish.

$$\left(-2\right)^{1}\left(-1\right)a^{2}a^{-2}$$

Ayni daraja ko'rsatkichlarini ko'paytirish uchun ularning darajalarini qo'shing.

$$\left(-2\right)^{1}\left(-1\right)a^{2-2}$$

2 va -2 belgilarini qo'shish.

$$\left(-2\right)^{1}\left(-1\right)a^{0}$$

-2 ni 1 daraja ko'rsatgichiga oshirish.

$$-2\left(-1\right)a^{0}$$

-2 ni -1 marotabaga ko'paytirish.

$$2a^{0}$$

Har qanday t sharti uchun (0 bundan mustasno) t^{0}=1.

$$2\times 1$$

Har qanday t sharti uchun t\times 1=t va 1t=t.

Eksponent koeffitsienti uchun qadamlar

Ifodani qisqartirish uchun eksponent qoidalaridan foydalanish.

$$\frac{\left(-2\right)^{1}a^{2}}{-a^{2}}$$

Ayni asosning daraja ko'rsatkichi bo'lish uchun maxrajning darajasini surat darajasidan bo'ling.

$$\frac{\left(-2\right)^{1}a^{2-2}}{-1}$$

2 dan 2 ni ayirish.

$$\frac{\left(-2\right)^{1}a^{0}}{-1}$$

Har qanday a raqami uchun (0 bundan mustasno) a^{0}=1.

$$\frac{\left(-2\right)^{1}}{-1}$$

-2 ni -1 ga bo'lish.
