### Example Question #1 : How To Add Exponents

Two quantities are given - one in Column A and the other in Column B. Compare the quantities in the two columns.

Assume, in both columns, that .

Column A Column B

**Possible Answers:**

The quantity in Column A is greater.

The relationship cannot be determined from the info given.

The quantity in Column B is greater.

The quantities in both columns are equal.

**Correct answer:**

The quantity in Column B is greater.

When you are adding and subtracting terms with exponents, you combine like terms. Since both columns have expressions with the same exponent throughout, you are good to just look at the coefficients. Remember, a coefficient is the number in front of a variable. Therefore, Column A is since . Column B is since . We can see that Column B is greater.
