Solve 4.7*1.6*10^-19=6.67*10^-34*A

$$4.7 \times 1.6 \times 10 ^ { - 19 } = 6.67 \times 10 ^ { - 34 } \times A$$

Solve for A

$$A=\frac{752000000000000000}{667}\approx 1.127436282 \cdot 10^{15}$$

Steps for Solving Linear Equation

Multiply 4.7 and 1.6 to get 7.52.

$$7.52\times 10^{-19}=6.67\times 10^{-34}A$$

Calculate 10 to the power of -19 and get \frac{1}{10000000000000000000}.

$$7.52\times \frac{1}{10000000000000000000}=6.67\times 10^{-34}A$$

Multiply 7.52 and \frac{1}{10000000000000000000} to get \frac{47}{62500000000000000000}.

$$\frac{47}{62500000000000000000}=6.67\times 10^{-34}A$$

Calculate 10 to the power of -34 and get \frac{1}{10000000000000000000000000000000000}.

$$\frac{47}{62500000000000000000}=6.67\times \frac{1}{10000000000000000000000000000000000}A$$

Multiply 6.67 and \frac{1}{10000000000000000000000000000000000} to get \frac{667}{1000000000000000000000000000000000000}.

$$\frac{47}{62500000000000000000}=\frac{667}{1000000000000000000000000000000000000}A$$

Swap sides so that all variable terms are on the left hand side.

$$\frac{667}{1000000000000000000000000000000000000}A=\frac{47}{62500000000000000000}$$

Multiply both sides by \frac{1000000000000000000000000000000000000}{667}, the reciprocal of \frac{667}{1000000000000000000000000000000000000}.

$$A=\frac{47}{62500000000000000000}\times \frac{1000000000000000000000000000000000000}{667}$$

Multiply \frac{47}{62500000000000000000} and \frac{1000000000000000000000000000000000000}{667} to get \frac{752000000000000000}{667}.

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