Ko'paytirishning kommutativ xususiyatdan foydalanish qadamlari

Ifodani qisqartirish uchun eksponent qoidalaridan foydalanish.

$$t^{3}u^{2}\times \frac{1}{t}u^{0}u^{-7}t^{1}$$

Ko'paytirishning kommutativ xususiyatidan foydalanish.

$$t^{3}u^{0}u^{2}u^{-7}\times \frac{1}{t}t^{1}$$

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

$$t^{3}u^{0}u^{2-7}t^{-1+1}$$

2 va -7 belgilarini qo'shish.

$$t^{3}u^{0}u^{-5}t^{-1+1}$$

-1 va 1 belgilarini qo'shish.

$$t^{3}u^{0}\times \frac{1}{u^{5}}t^{0}$$

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