Solve (-1.8*10^-10)div(9*10^8)

$$( - 1.8 \times 10 ^ { - 10 } ) \div ( 9 \times 10 ^ { 8 } )$$

Evaluate

$$-0.0000000000000000002$$

Solution Steps

To divide powers of the same base, subtract the numerator's exponent from the denominator's exponent.

$$\frac{-1.8}{9\times 10^{18}}$$

Calculate 10 to the power of 18 and get 1000000000000000000.

$$\frac{-1.8}{9\times 1000000000000000000}$$

Multiply 9 and 1000000000000000000 to get 9000000000000000000.

$$\frac{-1.8}{9000000000000000000}$$

Expand \frac{-1.8}{9000000000000000000} by multiplying both numerator and the denominator by 10.

$$\frac{-18}{90000000000000000000}$$

Reduce the fraction \frac{-18}{90000000000000000000} to lowest terms by extracting and canceling out 18.

$$-\frac{1}{5000000000000000000}$$

Factor

$$-0.0000000000000000002$$
