#9.3 xx 10^7#

The decimal point is to the right of the last zero, so move it to the left until you get in between the #9 and 3#, so that there is only one digit to the left.

That's #7# spaces, so your answer will be #9.3 xx 10^7.#

Scientific notation will always be written as #" a number" xx 10# raised to a power.

The number will be between #1 and 10#

In case you ever have a scenario when your decimal moves the other way, the exponent then would be negative. For now your exponent is positive.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
