Yechim qadamlari

-32 olish uchun -36 va 4'ni qo'shing.

$$\sqrt{-32}\sqrt{-9}$$

Faktor: -32=\left(4i\right)^{2}\times 2. \sqrt{\left(4i\right)^{2}\times 2} koʻpaytmasining kvadrat ildizini \sqrt{\left(4i\right)^{2}}\sqrt{2} kvadrat ildizlarining koʻpaytmasi sifatida qayta yozing. \left(4i\right)^{2} ning kvadrat ildizini chiqarish.

$$4i\sqrt{2}\sqrt{-9}$$

-9 ning kvadrat ildizini hisoblab, 3i natijaga ega bo‘ling.

$$4i\sqrt{2}\times \left(3i\right)$$

-12 hosil qilish uchun 4i va 3i ni ko'paytirish.

$$-12\sqrt{2}$$
