Example Questions
Example Question #1 : Exponential Operations
Which of the following is equal to the expression 
, where
xyz ≠ 0?
z
z/(xy)
1/y
xy
xyz
1/y
(xy)4 can be rewritten as x4y4 and z0 = 1 because a number to the zero power equals 1. After simplifying, you get 1/y.
Example Question #2 : Exponential Operations
If 
Cannot be determined
Start by simplifying the numerator and denominator separately. In the numerator, (c3)2 is equal to c6. In the denominator, c2 * c4 equals c6 as well. Dividing the numerator by the denominator, c6/c6, gives an answer of 1, because the numerator and the denominator are the equivalent.
Example Question #3 : Exponential Operations
If 
a
a4
a18
a6
The answer cannot be determined from the above information
a18
The numerator is simplified to 
Example Question #2311 : Sat Mathematics
When dividing exponents, we need to make sure we have the same base. In this case we do. Then we just subtract the exponents. The answer is 
Example Question #2312 : Sat Mathematics
When dividing exponents, we need to make sure we have the same base. In this case we do. Then we just subtract the exponents. The answer is 
Example Question #2313 : Sat Mathematics
None of the possible answers
None of the possible answers
When dividing exponents, we need to make sure we have the same base. In this case we don't. We can't really simplify it and we can't subtract with different bases so the answer is none of the possible answers.
Example Question #14 : How To Divide Exponents
When dividing exponents, we need to make sure we have the same base. In this case we do. Then we just subtract the exponents. The answer is 
Example Question #2314 : Sat Mathematics
When dividing exponents, we need to make sure we have the same base. In this case we do. Then we just subtract the exponents. Since we arre subtracting wit a negative alue, this becomes an addition problem. The answer is 
Example Question #133 : Exponential Operations
When dividing exponents, we need to make sure we have the same base. In this case we do. Since we are subtracting with a negative value, then it becomes addition. So far, we have 
Example Question #2315 : Sat Mathematics
When dividing exponents, we need to make sure we have the same base. In this case we do. Then we just subtract the exponents. Since we are subtracting a positive value, the sign becomes negative. We treat the expression as addition but the answer is negative. The answer is
