Baholash

$$-18$$

Yechim qadamlari

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

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

Ta’rifi bo‘yicha, i^{2} – bu -1.

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

Ko‘paytirishlarni bajaring.

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

Ta’rifi bo‘yicha, i^{2} – bu -1.

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

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

$$Re(-9+9i-9i-9)$$

-9+9i-9i-9 ichida real va mavhum qismlarni birlashtiring.

$$Re(-9-9+\left(9-9\right)i)$$

-9-9+\left(9-9\right)i ichida qo‘shishlarni bajaring.

$$Re(-18)$$

-18 ning real qismi – -18.
