Because you need it to be,
$1.4\times 10^{2.5+1=3.5}$
You need decimal point after the 1.

3. Hello, starslacker!

$14 \times 10^{2.5}$ . Why is this not standard form?

In standard form, the first number must be between 1 and 10
. . (greater than or equal to 1, but less than 10)

Standard form would be: . $1.4 \times 10^{3.5}$
