Datrys 218*10^-18quadx=663*10^-34*3*10^8/434*10^-9

$$218 \times 10 ^ { - 18 } \quad x = \frac { 663 \times 10 ^ { - 34 } \times 3 \times 10 ^ { 8 } } { 434 \times 10 ^ { - 9 } }$$

Datrys ar gyfer x

$$x=\frac{9945}{47306}\approx 0.210227033$$

Camau ar gyfer Datrys Hafaliad Llinol

Er mwyn lluosi pwerau sy’n rhannu’r un sail, adiwch eu esbonyddion. Adiwch -34 a 8 i gael -26.

$$218\times 10^{-18}x=\frac{663\times 10^{-26}\times 3}{434\times 10^{-9}}$$

Cyfrifo 10 i bŵer -18 a chael \frac{1}{1000000000000000000}.

$$218\times \frac{1}{1000000000000000000}x=\frac{663\times 10^{-26}\times 3}{434\times 10^{-9}}$$

Lluosi 218 a \frac{1}{1000000000000000000} i gael \frac{109}{500000000000000000}.

$$\frac{109}{500000000000000000}x=\frac{663\times 10^{-26}\times 3}{434\times 10^{-9}}$$

Er mwyn rhannu pwerau sy’n rhannu’r un sail, tynnwch esbonydd yr enwadur o esbonydd y rhifiadur.

$$\frac{109}{500000000000000000}x=\frac{3\times 663}{434\times 10^{17}}$$

Lluosi 3 a 663 i gael 1989.

$$\frac{109}{500000000000000000}x=\frac{1989}{434\times 10^{17}}$$

Cyfrifo 10 i bŵer 17 a chael 100000000000000000.

$$\frac{109}{500000000000000000}x=\frac{1989}{434\times 100000000000000000}$$

Lluosi 434 a 100000000000000000 i gael 43400000000000000000.

$$\frac{109}{500000000000000000}x=\frac{1989}{43400000000000000000}$$

Lluoswch y ddwy ochr â \frac{500000000000000000}{109}, cilyddol \frac{109}{500000000000000000}.

$$x=\frac{1989}{43400000000000000000}\times \frac{500000000000000000}{109}$$

Lluosi \frac{1989}{43400000000000000000} a \frac{500000000000000000}{109} i gael \frac{9945}{47306}.

$$x=\frac{9945}{47306}$$
