$3.2 \times {10}^{4}$

#### Explanation:

A number in scientific notation is of the form $a \times {10}^{n}$

where 1 ≤ a < 10 and n is an integer

writing 32 000 as a number between 1 and 10 is 3.2

To get number back into it's original form means multiplying 3.2 by 10 000

$\Rightarrow 32 000 = 3.2 \times {10}^{4}$
