If two or more choices can be eliminated, make an educated guess among the remaining answer choices. When possible, try to reduce the guessing to among two or three choices.

**Use this approach sparingly and only when pressed for time.**

**Example:**

Which of the following cannot be simplified further?

(A)

(B)

(C)

(D)

(E)

**(D) is the correct answer.**

We can best solve this problem by the Elimination approach. Look carefully at each answer choice and try to eliminate all but one.

We can simplify a square root if it contains a perfect square. In this problem we can simplify (A), (B), and (E) by recognizing the perfect squares they contain:

(A)

(B)

(C) Simplify by multiplying:

(D) Different numbers are under the square root sign, so they cannot be added. Furthermore, neither radical can be simplified.

(E)
