Datrys (3/4)^2+(4/5)^2=

$$( \frac { 3 } { 4 } ) ^ { 2 } + ( \frac { 4 } { 5 } ) ^ { 2 } =$$

Enrhifo

$$\frac{481}{400}=1.2025$$

Camau Ateb

Cyfrifo \frac{3}{4} i bŵer 2 a chael \frac{9}{16}.

$$\frac{9}{16}+\left(\frac{4}{5}\right)^{2}$$

Cyfrifo \frac{4}{5} i bŵer 2 a chael \frac{16}{25}.

$$\frac{9}{16}+\frac{16}{25}$$

Lluosrif lleiaf cyffredin 16 a 25 yw 400. Troswch \frac{9}{16} a \frac{16}{25} yn ffracsiynau gyda’r enwadur 400.

$$\frac{225}{400}+\frac{256}{400}$$

Gan fod gan \frac{225}{400} a \frac{256}{400} yr un dynodydd, adiwch nhw drwy adio eu rhifiaduron.

$$\frac{225+256}{400}$$

Adio 225 a 256 i gael 481.

$$\frac{481}{400}$$

Ffactor

$$\frac{13 \cdot 37}{2 ^ {4} \cdot 5 ^ {2}} = 1\frac{81}{400} = 1.2025$$
