# How do you write 1.91 times 10^-3  in standard notation?

Apr 6, 2018

$1.91 \times {10}^{-} 3 = 0.00191$

#### Explanation:

Standard notation is a number simply written with numeric digits.

${10}^{-} 3$ can be written $0.001$, therefore

$1.91 \times {10}^{-} 3$ can be written $1.91 \times 0.001$.

Multiplying $1.91 \text{ by } 0.001$ yields 0.00191.

I hope this helps,
