CB=\sqrt{49+7^{2}}

2 daraja ko‘rsatkichini 7 ga hisoblang va 49 ni qiymatni oling.

CB=\sqrt{49+49}

2 daraja ko‘rsatkichini 7 ga hisoblang va 49 ni qiymatni oling.

CB=\sqrt{98}

98 olish uchun 49 va 49'ni qo'shing.

CB=7\sqrt{2}

Faktor: 98=7^{2}\times 2. \sqrt{7^{2}\times 2} koʻpaytmasining kvadrat ildizini \sqrt{7^{2}}\sqrt{2} kvadrat ildizlarining koʻpaytmasi sifatida qayta yozing. 7^{2} ning kvadrat ildizini chiqarish.

\frac{CB}{C}=\frac{7\sqrt{2}}{C}

Ikki tarafini C ga bo‘ling.

B=\frac{7\sqrt{2}}{C}

C ga bo'lish C ga ko'paytirishni bekor qiladi.

CB=\sqrt{49+7^{2}}

98 olish uchun 49 va 49'ni qo'shing.

CB=7\sqrt{2}

Faktor: 98=7^{2}\times 2. \sqrt{7^{2}\times 2} koʻpaytmasining kvadrat ildizini \sqrt{7^{2}}\sqrt{2} kvadrat ildizlarining koʻpaytmasi sifatida qayta yozing. 7^{2} ning kvadrat ildizini chiqarish.

BC=7\sqrt{2}

Tenglama standart shaklda.

\frac{BC}{B}=\frac{7\sqrt{2}}{B}

Ikki tarafini B ga bo‘ling.

C=\frac{7\sqrt{2}}{B}

B ga bo'lish B ga ko'paytirishni bekor qiladi.
