\frac{7\left(\sqrt{3}+\sqrt{2}\right)}{\left(\sqrt{3}-\sqrt{2}\right)\left(\sqrt{3}+\sqrt{2}\right)}
\frac{7}{\sqrt{3}-\sqrt{2}} maxrajini \sqrt{3}+\sqrt{2} orqali surat va maxrajini koʻpaytirish orqali ratsionallashtiring.
\frac{7\left(\sqrt{3}+\sqrt{2}\right)}{\left(\sqrt{3}\right)^{2}-\left(\sqrt{2}\right)^{2}}
Hisoblang: \left(\sqrt{3}-\sqrt{2}\right)\left(\sqrt{3}+\sqrt{2}\right). Ko‘paytirish qoida yordamida turli kvadratlarga aylantirilishi mumkin: \left(a-b\right)\left(a+b\right)=a^{2}-b^{2}.
\frac{7\left(\sqrt{3}+\sqrt{2}\right)}{3-2}
\sqrt{3} kvadratini chiqarish. \sqrt{2} kvadratini chiqarish.
\frac{7\left(\sqrt{3}+\sqrt{2}\right)}{1}
1 olish uchun 3 dan 2 ni ayirish.
7\left(\sqrt{3}+\sqrt{2}\right)
