Solve 3*20^-1+1*10^-2+5*10^-4

$$3 \cdot 20 ^ { - 1 } + 1 \cdot 10 ^ { - 2 } + 5 \cdot 10 ^ { - 4 }$$

Evaluate

$$\frac{321}{2000}=0.1605$$

Solution Steps

Calculate 20 to the power of -1 and get \frac{1}{20}.

$$3\times \frac{1}{20}+1\times 10^{-2}+5\times 10^{-4}$$

Multiply 3 and \frac{1}{20} to get \frac{3}{20}.

$$\frac{3}{20}+1\times 10^{-2}+5\times 10^{-4}$$

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

$$\frac{3}{20}+1\times \frac{1}{100}+5\times 10^{-4}$$

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

$$\frac{3}{20}+\frac{1}{100}+5\times 10^{-4}$$

Add \frac{3}{20} and \frac{1}{100} to get \frac{4}{25}.

$$\frac{4}{25}+5\times 10^{-4}$$

Calculate 10 to the power of -4 and get \frac{1}{10000}.

$$\frac{4}{25}+5\times \frac{1}{10000}$$

Multiply 5 and \frac{1}{10000} to get \frac{1}{2000}.

$$\frac{4}{25}+\frac{1}{2000}$$

Add \frac{4}{25} and \frac{1}{2000} to get \frac{321}{2000}.

$$\frac{321}{2000}$$

Factor

$$\frac{3 \cdot 107}{2 ^ {4} \cdot 5 ^ {3}} = 0.1605$$
