Datrys sqrt{5^2+{left(5/3right)}^2}

$$\sqrt{ { 5 }^{ 2 } + { \left( \frac{ 5 }{ 3 } \right) }^{ 2 } }$$

Enrhifo

$$\frac{5\sqrt{10}}{3}\approx 5.270462767$$

Camau Ateb

Cyfrifo 5 i bŵer 2 a chael 25.

$$\sqrt{25+\left(\frac{5}{3}\right)^{2}}$$

Cyfrifo \frac{5}{3} i bŵer 2 a chael \frac{25}{9}.

$$\sqrt{25+\frac{25}{9}}$$

Troswch y rhif degol 25 i’r ffracsiwn \frac{225}{9}.

$$\sqrt{\frac{225}{9}+\frac{25}{9}}$$

Gan fod gan \frac{225}{9} a \frac{25}{9} yr un dynodydd, adiwch nhw drwy adio eu rhifiaduron.

$$\sqrt{\frac{225+25}{9}}$$

Adio 225 a 25 i gael 250.

$$\sqrt{\frac{250}{9}}$$

Ailysgrifennu ail isradd y rhaniad \sqrt{\frac{250}{9}} fel rhaniad ail israddau \frac{\sqrt{250}}{\sqrt{9}}.

$$\frac{\sqrt{250}}{\sqrt{9}}$$

Ffactora 250=5^{2}\times 10. Ailysgrifennu ail isradd y lluoswm \sqrt{5^{2}\times 10} fel lluoswm ail israddau \sqrt{5^{2}}\sqrt{10}. Cymryd isradd 5^{2}.

$$\frac{5\sqrt{10}}{\sqrt{9}}$$

Cyfrifo ail isradd 9 a chael 3.

$$\frac{5\sqrt{10}}{3}$$
