Decimal Notation

0.000162

Solution steps

(2 \cdot 1 0^{- 4}) (8.1 \cdot 1 0^{- 1})

Simplify

2 \cdot 1 0^{- 4} : \frac{1}{5000}

= \frac{1}{5000} \cdot 8.1 \cdot 1 0^{- 1}

Apply exponent rule:

a^{- 1} = \frac{1}{a}

1 0^{- 1} = \frac{1}{10}

= \frac{1}{5000} \cdot 8.1 \cdot \frac{1}{10}

8.1 = \frac{81}{10}

= \frac{1}{5000} \cdot \frac{81}{10} \cdot \frac{1}{10}

\frac{1}{5000} \cdot \frac{81}{10} \cdot \frac{1}{10} = \frac{81}{500000}

= \frac{81}{500000}
