Solve 7*10^-4-1*10^-4

$$7 \times { 10 }^{ -4 } -1 \times { 10 }^{ -4 }$$

Evaluate

$$\frac{3}{5000}=0.0006$$

Solution Steps

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

$$7\times \frac{1}{10000}-1\times 10^{-4}$$

Multiply 7 and \frac{1}{10000} to get \frac{7}{10000}.

$$\frac{7}{10000}-1\times 10^{-4}$$

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

$$\frac{7}{10000}-1\times \frac{1}{10000}$$

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

$$\frac{7}{10000}-\frac{1}{10000}$$

Subtract \frac{1}{10000} from \frac{7}{10000} to get \frac{3}{5000}.

$$\frac{3}{5000}$$

Factor

$$\frac{3}{2 ^ {3} \cdot 5 ^ {4}} = 0.0006$$
