Datrys 2x(y%)(y%)

$$2x(y \% )(y \% )$$

Enrhifo

$$\frac{xy^{2}}{5000}$$

Camau Ateb

Lluosi \frac{y}{100} a \frac{y}{100} i gael \left(\frac{y}{100}\right)^{2}.

$$2x\times \left(\frac{y}{100}\right)^{2}$$

I godi \frac{y}{100} i bŵer, codwch y rhifiadur a'r enwadur i bŵer ac yna rhannwch nhw.

$$2x\times \frac{y^{2}}{100^{2}}$$

Mynegwch 2\times \frac{y^{2}}{100^{2}} fel ffracsiwn unigol.

$$\frac{2y^{2}}{100^{2}}x$$

Cyfrifo 100 i bŵer 2 a chael 10000.

$$\frac{2y^{2}}{10000}x$$

Rhannu 2y^{2} â 10000 i gael \frac{1}{5000}y^{2}.

$$\frac{1}{5000}y^{2}x$$

Gwahaniaethu w.r.t. x

$$\frac{y^{2}}{5000}$$
