For this case we have the following expression:

We note that, we have a 4-digit number divided by a number of 1 digit other than 1.
Therefore, the answer must be at least 3 digits.
Thus, the first number of the quotient is located in hundreds place.
To verify this answer, we make the division with a calculator:

We observe that indeed, the first number of the quotient is located in hundreds place.
Answer:
the first number of the quotient is located in hundreds place
14% of $15,500 is $2,170. $15,500 minus $2,170 is $13,330.
When the car is on sale, the price is reduced from $15,500 to $13,330.
Standard form would be 1.46e-6 because the variable has one degree and the number 6 does not have a degree.
(n-7) (n-7) will be your answer
n x n = n²
n x -7 = -7n
n x - 7 = -7n
-7n +(-7n) = -14n
-7 x -7 = 49
(n-7)² is your answer

and if you are doing the other thing
n = 7, 7
