Solve 2*10^-2+3*10^-3

$$2 \times 10 ^ { - 2 } + 3 \times 10 ^ { - 3 }$$

Evaluate

$$\frac{23}{1000}=0.023$$

Solution Steps

Calculate 10 to the power of -2 and get \frac{1}{100}.

$$2\times \frac{1}{100}+3\times 10^{-3}$$

Multiply 2 and \frac{1}{100} to get \frac{1}{50}.

$$\frac{1}{50}+3\times 10^{-3}$$

Calculate 10 to the power of -3 and get \frac{1}{1000}.

$$\frac{1}{50}+3\times \frac{1}{1000}$$

Multiply 3 and \frac{1}{1000} to get \frac{3}{1000}.

$$\frac{1}{50}+\frac{3}{1000}$$

Add \frac{1}{50} and \frac{3}{1000} to get \frac{23}{1000}.

$$\frac{23}{1000}$$

Factor

$$\frac{23}{2 ^ {3} \cdot 5 ^ {3}} = 0.023$$
