Rešite 47*10^-19=663*10^-34*3*10^8/2*10^-7-w

$$47 \times 10 ^ { - 19 } = 663 \times 10 ^ { - 34 } \times \frac { 3 \times 10 ^ { 8 } } { 2 \times 10 ^ { - 7 } } - w$$

Rešitev za w

$$w=\frac{379}{4000000000000000000}=9,475 \cdot 10^{-17}$$

Delite 3000000000000000 s/z 2, da dobite 1500000000000000.

$$\frac{47}{10000000000000000000}=\frac{663}{10000000000000000000000000000000000}\times 1500000000000000-w$$

Pomnožite \frac{663}{10000000000000000000000000000000000} in 1500000000000000, da dobite \frac{1989}{20000000000000000000}.

$$\frac{47}{10000000000000000000}=\frac{1989}{20000000000000000000}-w$$

Zamenjajte strani tako, da so vse spremenljivke na levi strani.

$$\frac{1989}{20000000000000000000}-w=\frac{47}{10000000000000000000}$$

Odštejte \frac{1989}{20000000000000000000} na obeh straneh.

$$-w=\frac{47}{10000000000000000000}-\frac{1989}{20000000000000000000}$$

Odštejte \frac{1989}{20000000000000000000} od \frac{47}{10000000000000000000}, da dobite -\frac{379}{4000000000000000000}.

$$-w=-\frac{379}{4000000000000000000}$$

Pomnožite obe strani z vrednostjo -1.
