Example Question #61 : How To Make Non Geometric Comparisons

Examine (a), (b), and (c) to find the best answer:

a) 

b) 

c) 

Possible Answers:

(a) equals (c) but not (b)

(a), (b), and (c) are all equal

(a) equals (b) but not (c)

(a), (b), and (c) are all unequal

Correct answer:

(a) equals (c) but not (b)

Explanation:

To compare the expressions, distribute and simplify:

a)  

b)  

c) 

It is now clear that (a) and (c) are equal but (b) is not.

Example Question #62 : How To Make Non Geometric Comparisons

Examine (a), (b), and (c) to find the best answer:

(a), (b), and (c) are all equal

(a), (b), and (c) are all unequal

(a) is equal to (c) but not (b)

(a) is equal to (b) but not (c)

Correct answer:

(a), (b), and (c) are all equal

Explanation:

The important property of square roots to remember here is that 

This means that (a) can be broken up into the following:

These variations are all equal

Example Question #63 : How To Make Non Geometric Comparisons

Examine (a), (b), and (c) to find the best answer:

a) 

b) 

c) 

Possible Answers:

Correct answer:

Explanation:

(a)  is exactly half of (b) , and is therefore smaller. (c)  is even smaller than both.

(a), (b), and (c) are all unequal

(a) is equal to (c) but not (b)

Correct answer:

(a) is equal to (b) but not (c)

Explanation:

(b) is a factored version of (a). (c), however, is not raised to the same exponent. Test this by plugging a number in for . Here, we try .

a) 

b) 

c) 

(a) and (b) are equal, but (c) is not.
