Solve 6*10^-5-4*10^-6

$$6 \times { 10 }^{ -5 } -4 \times { 10 }^{ -6 }$$

Evaluate

$$\frac{7}{125000}=0.000056$$

Solution Steps

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

$$6\times \frac{1}{100000}-4\times 10^{-6}$$

Multiply 6 and \frac{1}{100000} to get \frac{3}{50000}.

$$\frac{3}{50000}-4\times 10^{-6}$$

Calculate 10 to the power of -6 and get \frac{1}{1000000}.

$$\frac{3}{50000}-4\times \frac{1}{1000000}$$

Multiply 4 and \frac{1}{1000000} to get \frac{1}{250000}.

$$\frac{3}{50000}-\frac{1}{250000}$$

Subtract \frac{1}{250000} from \frac{3}{50000} to get \frac{7}{125000}.

$$\frac{7}{125000}$$

Factor

$$\frac{7}{2 ^ {3} \cdot 5 ^ {6}} = 5.6 \times 10^{-5}$$
