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

    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}
