To write a number in scientific notation, first write a decimal point in the number so that there is only 1 digit to the left of the decimal point.
Next, count the number of places the decimal point would need to move to get back to the original number.
The exponent would be positive because we need to move the decimal point to the right in order to get back to our original number.
Lastly, we can drop the zero at the end of the decimal.

To make sure we don't have negatives under the square root, we specify that
(x is greater than or equal to 0). We'll use this fact later on
--------------------------------------------
Start with the given inequality
and square both sides to get
. Couple this with the fact that
means we have this compound inequality
What does this mean? It means that we can pick any value from 0 to 49 (including both endpoints) and it will be a solution to the inequality. This applies to the values
