Solve 52*10^-2+42*10^-3

$$52 \times 10 ^ { - 2 } + 42 \times 10 ^ { - 3 }$$

Evaluate

$$\frac{281}{500}=0.562$$

Solution Steps

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

$$52\times \frac{1}{100}+42\times 10^{-3}$$

Multiply 52 and \frac{1}{100} to get \frac{13}{25}.

$$\frac{13}{25}+42\times 10^{-3}$$

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

$$\frac{13}{25}+42\times \frac{1}{1000}$$

Multiply 42 and \frac{1}{1000} to get \frac{21}{500}.

$$\frac{13}{25}+\frac{21}{500}$$

Add \frac{13}{25} and \frac{21}{500} to get \frac{281}{500}.

$$\frac{281}{500}$$

Factor

$$\frac{281}{2 ^ {2} \cdot 5 ^ {3}} = 0.562$$
