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

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

Evaluate

$$\frac{43}{100}=0.43$$

Solution Steps

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

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

Multiply 4 and \frac{1}{10} to get \frac{2}{5}.

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

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

$$\frac{2}{5}+3\times \frac{1}{100}$$

Multiply 3 and \frac{1}{100} to get \frac{3}{100}.

$$\frac{2}{5}+\frac{3}{100}$$

Add \frac{2}{5} and \frac{3}{100} to get \frac{43}{100}.

$$\frac{43}{100}$$

Factor

$$\frac{43}{2 ^ {2} \cdot 5 ^ {2}} = 0.43$$
