Løs 47*1610^-19=667*10^-34*A

$$47 \cdot 16 { 10 }^{ -19 } = 667 \times { 10 }^{ -34 } \times A$$

Løs for A

$$A=\frac{752000000000000000}{667}\approx 1,127436282 \cdot 10^{15}$$

Vejledning i at løse lineær ligning

Multiplicer 47 og 16 for at få 752.

$$752\times 10^{-19}=667\times 10^{-34}A$$

Beregn 10 til potensen af -19, og få \frac{1}{10000000000000000000}.

$$752\times \frac{1}{10000000000000000000}=667\times 10^{-34}A$$

Multiplicer 752 og \frac{1}{10000000000000000000} for at få \frac{47}{625000000000000000}.

$$\frac{47}{625000000000000000}=667\times 10^{-34}A$$

Beregn 10 til potensen af -34, og få \frac{1}{10000000000000000000000000000000000}.

$$\frac{47}{625000000000000000}=667\times \frac{1}{10000000000000000000000000000000000}A$$

Multiplicer 667 og \frac{1}{10000000000000000000000000000000000} for at få \frac{667}{10000000000000000000000000000000000}.

$$\frac{47}{625000000000000000}=\frac{667}{10000000000000000000000000000000000}A$$

Skift side, så alle variable led er placeret på venstre side.

$$\frac{667}{10000000000000000000000000000000000}A=\frac{47}{625000000000000000}$$

Multiplicer begge sider med \frac{10000000000000000000000000000000000}{667}, den reciprokke af \frac{667}{10000000000000000000000000000000000}.

$$A=\frac{47}{625000000000000000}\times \frac{10000000000000000000000000000000000}{667}$$

Multiplicer \frac{47}{625000000000000000} og \frac{10000000000000000000000000000000000}{667} for at få \frac{752000000000000000}{667}.

$$A=\frac{752000000000000000}{667}$$
