Solve 23*10^-2+27*10^-1

$$23 \times { 10 }^{ -2 } +27 \times { 10 }^{ -1 }$$

Evaluate

$$\frac{293}{100}=2.93$$

Solution Steps

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

$$23\times \frac{1}{100}+27\times 10^{-1}$$

Multiply 23 and \frac{1}{100} to get \frac{23}{100}.

$$\frac{23}{100}+27\times 10^{-1}$$

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

$$\frac{23}{100}+27\times \frac{1}{10}$$

Multiply 27 and \frac{1}{10} to get \frac{27}{10}.

$$\frac{23}{100}+\frac{27}{10}$$

Add \frac{23}{100} and \frac{27}{10} to get \frac{293}{100}.

$$\frac{293}{100}$$

Factor

$$\frac{293}{2 ^ {2} \cdot 5 ^ {2}} = 2\frac{93}{100} = 2.93$$
