# How do you write 6.5 times 10^-4 in standard notation?

Apr 6, 2016

$6.5 \times {10}^{- 4} = 0.00065$

#### Explanation:

Note ${10}^{0} = 1$

$6.5 \times {10}^{0} = 6.5$

$6.5 \times {10}^{- 1} = 0.65$

$6.5 \times {10}^{- 2} = 0.065$

$6.5 \times {10}^{- 3} = 0.0065$

$6.5 \times {10}^{- 4} = 0.00065$

each reduction of the exponent of $10$ moves the decimal point one position to the left.
