2+5i-2i(3+2i) eching

$$2 + 5 i - 2 i ( 3 + 2 i )$$

Baholash

$$6-i$$

Yechim qadamlari

2i ni 3+2i marotabaga ko'paytirish.

$$2+5i-\left(2i\times 3+2\times 2i^{2}\right)$$

Ta’rifi bo‘yicha, i^{2} – bu -1.

$$2+5i-\left(2i\times 3+2\times 2\left(-1\right)\right)$$

2i\times 3+2\times 2\left(-1\right) ichidagi ko‘paytirishlarni bajaring. Shartlarni qayta saralash.

$$2+5i-\left(-4+6i\right)$$

-4+6i ni 2+5i dan mos real va mavhum qismlarni ayirish orqali ayiring.

$$2-\left(-4\right)+\left(5-6\right)i$$

2 dan -4 ni ayirish. 5 dan 6 ni ayirish.

$$6-i$$

Ashyoviy qism

$$6$$

Yechim qadamlari

2i ni 3+2i marotabaga ko'paytirish.

$$Re(2+5i-\left(2i\times 3+2\times 2i^{2}\right))$$

Ta’rifi bo‘yicha, i^{2} – bu -1.

$$Re(2+5i-\left(2i\times 3+2\times 2\left(-1\right)\right))$$

2i\times 3+2\times 2\left(-1\right) ichidagi ko‘paytirishlarni bajaring. Shartlarni qayta saralash.

$$Re(2+5i-\left(-4+6i\right))$$

-4+6i ni 2+5i dan mos real va mavhum qismlarni ayirish orqali ayiring.

$$Re(2-\left(-4\right)+\left(5-6\right)i)$$

2 dan -4 ni ayirish. 5 dan 6 ni ayirish.

$$Re(6-i)$$

6-i ning real qismi – 6.

$$6$$
