Solve 2*10^-6+7*10^-6

$$2 \times 10 ^ { - 6 } + 7 \times 10 ^ { - 6 }$$

Evaluate

$$\frac{9}{1000000}=0.000009$$

Solution Steps

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

$$2\times \frac{1}{1000000}+7\times 10^{-6}$$

Multiply 2 and \frac{1}{1000000} to get \frac{1}{500000}.

$$\frac{1}{500000}+7\times 10^{-6}$$

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

$$\frac{1}{500000}+7\times \frac{1}{1000000}$$

Multiply 7 and \frac{1}{1000000} to get \frac{7}{1000000}.

$$\frac{1}{500000}+\frac{7}{1000000}$$

Add \frac{1}{500000} and \frac{7}{1000000} to get \frac{9}{1000000}.

$$\frac{9}{1000000}$$

Factor

$$\frac{3 ^ {2}}{2 ^ {6} \cdot 5 ^ {6}} = 9 \times 10^{-6}$$
