Solve (3,1*10^5)*(2*10^-7)

$$( 3,1 \cdot 10 ^ { 5 } ) \cdot ( 2 \cdot 10 ^ { - 7 } )$$

Evaluate

$$0,062$$

Solution Steps

To multiply powers of the same base, add their exponents. Add 5 and -7 to get -2.

$$3,1\times 10^{-2}\times 2$$

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

$$3,1\times \frac{1}{100}\times 2$$

Multiply 3,1 and \frac{1}{100} to get \frac{31}{1000}.

$$\frac{31}{1000}\times 2$$

Multiply \frac{31}{1000} and 2 to get \frac{31}{500}.

$$\frac{31}{500}$$

Factor

$$\frac{31}{2 ^ {2} \cdot 5 ^ {3}} = 0.062$$
