Solve 5*10^-4-3*10^-5

$$5 \times 10 ^ { - 4 } - 3 \times 10 ^ { - 5 }$$

Evaluate

$$\frac{47}{100000}=0.00047$$

Solution Steps

Calculate 10 to the power of -4 and get \frac{1}{10000}.

$$5\times \frac{1}{10000}-3\times 10^{-5}$$

Multiply 5 and \frac{1}{10000} to get \frac{1}{2000}.

$$\frac{1}{2000}-3\times 10^{-5}$$

Calculate 10 to the power of -5 and get \frac{1}{100000}.

$$\frac{1}{2000}-3\times \frac{1}{100000}$$

Multiply 3 and \frac{1}{100000} to get \frac{3}{100000}.

$$\frac{1}{2000}-\frac{3}{100000}$$

Subtract \frac{3}{100000} from \frac{1}{2000} to get \frac{47}{100000}.

$$\frac{47}{100000}$$

Factor

$$\frac{47}{2 ^ {5} \cdot 5 ^ {5}} = 0.00047$$
