Solve (1.9*10^-6)+(2*10^-5)

$$(1.9 \times { 10 }^{ -6 } )+(2 \times { 10 }^{ -5 } )$$

Evaluate

$$0.0000219$$

Solution Steps

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

$$1.9\times \frac{1}{1000000}+2\times 10^{-5}$$

Multiply 1.9 and \frac{1}{1000000} to get \frac{19}{10000000}.

$$\frac{19}{10000000}+2\times 10^{-5}$$

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

$$\frac{19}{10000000}+2\times \frac{1}{100000}$$

Multiply 2 and \frac{1}{100000} to get \frac{1}{50000}.

$$\frac{19}{10000000}+\frac{1}{50000}$$

Add \frac{19}{10000000} and \frac{1}{50000} to get \frac{219}{10000000}.

$$\frac{219}{10000000}$$

Factor

$$\frac{3 \cdot 73}{2 ^ {7} \cdot 5 ^ {7}} = 2.19 \times 10^{-5}$$
