(-8+3i)(-4+4i)= eching

$$( - 8 + 3 i ) ( - 4 + 4 i ) =$$

Baholash

$$20-44i$$

Yechim qadamlari

Binomlarni ko‘paytirgandek -8+3i va -4+4i murakkab sonlarni ko‘paytiring.

$$-8\left(-4\right)-8\times \left(4i\right)+3i\left(-4\right)+3\times 4i^{2}$$

Ta’rifi bo‘yicha, i^{2} – bu -1.

$$-8\left(-4\right)-8\times \left(4i\right)+3i\left(-4\right)+3\times 4\left(-1\right)$$

Ko‘paytirishlarni bajaring.

$$32-32i-12i-12$$

Real va mavhum qismlarni birlashtiring.

$$32-12+\left(-32-12\right)i$$

Qo‘shishlarni bajaring.

$$20-44i$$

Ashyoviy qism

$$20$$

Yechim qadamlari

Binomlarni ko‘paytirgandek -8+3i va -4+4i murakkab sonlarni ko‘paytiring.

$$Re(-8\left(-4\right)-8\times \left(4i\right)+3i\left(-4\right)+3\times 4i^{2})$$

Ta’rifi bo‘yicha, i^{2} – bu -1.

$$Re(-8\left(-4\right)-8\times \left(4i\right)+3i\left(-4\right)+3\times 4\left(-1\right))$$

-8\left(-4\right)-8\times \left(4i\right)+3i\left(-4\right)+3\times 4\left(-1\right) ichidagi ko‘paytirishlarni bajaring.

$$Re(32-32i-12i-12)$$

32-32i-12i-12 ichida real va mavhum qismlarni birlashtiring.

$$Re(32-12+\left(-32-12\right)i)$$

32-12+\left(-32-12\right)i ichida qo‘shishlarni bajaring.

$$Re(20-44i)$$

20-44i ning real qismi – 20.
