Datrys 1600/10^-5*2=10^4*2x

$$\frac { 1600 } { 10 ^ { - 5 } \times 2 } = 10 ^ { 4 } \times 2 x$$

Datrys ar gyfer x

$$x=4000$$

Camau ar gyfer Datrys Hafaliad Llinol

Cyfrifo 10 i bŵer -5 a chael \frac{1}{100000}.

$$\frac{1600}{\frac{1}{100000}\times 2}=10^{4}\times 2x$$

Lluosi \frac{1}{100000} a 2 i gael \frac{1}{50000}.

$$\frac{1600}{\frac{1}{50000}}=10^{4}\times 2x$$

Rhannwch 1600 â \frac{1}{50000} drwy luosi 1600 â chilydd \frac{1}{50000}.

$$1600\times 50000=10^{4}\times 2x$$

Lluosi 1600 a 50000 i gael 80000000.

$$80000000=10^{4}\times 2x$$

Cyfrifo 10 i bŵer 4 a chael 10000.

$$80000000=10000\times 2x$$

Lluosi 10000 a 2 i gael 20000.

$$80000000=20000x$$

Cyfnewidiwch yr ochrau fel bod yr holl dermau newidiol ar yr ochr chwith.

$$20000x=80000000$$

Rhannu’r ddwy ochr â 20000.

$$x=\frac{80000000}{20000}$$

Rhannu 80000000 â 20000 i gael 4000.

$$x=4000$$
