Datrys frac{frac{sqrt{2}}{2}+3^2}{21}

$$\frac { \frac { \sqrt { 2 } } { 2 } + 3 ^ { 2 } } { 21 }$$

Enrhifo

$$\frac{\sqrt{2}}{42}+\frac{3}{7}\approx 0.46224318$$

Camau Ateb Byr

Cyfrifo 3 i bŵer 2 a chael 9.

$$\frac{\frac{\sqrt{2}}{2}+9}{21}$$

I ychwanegu neu dynnu mynegiannau, rhaid i chi eu ehangu i wneud eu enwaduron yr un fath. Lluoswch 9 â \frac{2}{2}.

$$\frac{\frac{\sqrt{2}}{2}+\frac{9\times 2}{2}}{21}$$

Gan fod gan \frac{\sqrt{2}}{2} a \frac{9\times 2}{2} yr un dynodydd, adiwch nhw drwy adio eu rhifiaduron.

$$\frac{\frac{\sqrt{2}+9\times 2}{2}}{21}$$

Gwnewch y gwaith lluosi yn \sqrt{2}+9\times 2.

$$\frac{\frac{\sqrt{2}+18}{2}}{21}$$

Mynegwch \frac{\frac{\sqrt{2}+18}{2}}{21} fel ffracsiwn unigol.

$$\frac{\sqrt{2}+18}{2\times 21}$$

Lluosi 2 a 21 i gael 42.

$$\frac{\sqrt{2}+18}{42}$$

Ffactor

$$\frac{\sqrt{2} + 18}{42} = 0.4622431800565023$$
