Solve 2.3*10^-9+9.4*10^-9

$$2.3 \times 10 ^ { - 9 } + 9.4 \times 10 ^ { - 9 }$$

Evaluate

$$0.0000000117$$

Solution Steps

Calculate 10 to the power of -9 and get \frac{1}{1000000000}.

$$2.3\times \frac{1}{1000000000}+9.4\times 10^{-9}$$

Multiply 2.3 and \frac{1}{1000000000} to get \frac{23}{10000000000}.

$$\frac{23}{10000000000}+9.4\times 10^{-9}$$

Calculate 10 to the power of -9 and get \frac{1}{1000000000}.

$$\frac{23}{10000000000}+9.4\times \frac{1}{1000000000}$$

Multiply 9.4 and \frac{1}{1000000000} to get \frac{47}{5000000000}.

$$\frac{23}{10000000000}+\frac{47}{5000000000}$$

Add \frac{23}{10000000000} and \frac{47}{5000000000} to get \frac{117}{10000000000}.

$$\frac{117}{10000000000}$$

Factor

$$\frac{13 \cdot 3 ^ {2}}{2 ^ {10} \cdot 5 ^ {10}} = 1.17 \times 10^{-8}$$
