Datrys 6+2^2*(-1/5)

$$6 + 2 ^ { 2 } \times ( - \frac { 1 } { 5 } )$$

Enrhifo

$$\frac{26}{5}=5.2$$

Camau Ateb

Cyfrifo 2 i bŵer 2 a chael 4.

$$6+4\left(-\frac{1}{5}\right)$$

Mynegwch 4\left(-\frac{1}{5}\right) fel ffracsiwn unigol.

$$6+\frac{4\left(-1\right)}{5}$$

Lluosi 4 a -1 i gael -4.

$$6+\frac{-4}{5}$$

Gellir ailysgrifennu \frac{-4}{5} fel -\frac{4}{5} drwy echdynnu’r arwydd negatif.

$$6-\frac{4}{5}$$

Troswch y rhif degol 6 i’r ffracsiwn \frac{30}{5}.

$$\frac{30}{5}-\frac{4}{5}$$

Gan fod gan \frac{30}{5} a \frac{4}{5} yr un dynodydd, tynnwch nhw drwy dynnu eu rhifiaduron.

$$\frac{30-4}{5}$$

Tynnu 4 o 30 i gael 26.

$$\frac{26}{5}$$

Ffactor

$$\frac{2 \cdot 13}{5} = 5\frac{1}{5} = 5.2$$
