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

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

Lahendage ja leidke x

$$x=\frac{9945}{47306}\approx 0,210227033$$

Juhised lineaarvõrrandi lahendamiseks

Sama alusega astmete korrutamiseks liitke astendajad. Liitke -34 ja 8, et saada -26.

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

Arvutage -18 aste 10 ja leidke \frac{1}{1000000000000000000}.

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

Korrutage 218 ja \frac{1}{1000000000000000000}, et leida \frac{109}{500000000000000000}.

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

Sama alusega astmete jagamiseks lahutage lugeja astendaja nimetaja astendajast.

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

Korrutage 3 ja 663, et leida 1989.

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

Arvutage 17 aste 10 ja leidke 100000000000000000.

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

Korrutage 434 ja 100000000000000000, et leida 43400000000000000000.

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

Korrutage mõlemad pooled \frac{500000000000000000}{109}-ga, mis on \frac{109}{500000000000000000} pöördväärtus.

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

Korrutage \frac{1989}{43400000000000000000} ja \frac{500000000000000000}{109}, et leida \frac{9945}{47306}.

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