# For Exercises 7 and 8, use the Trichotomy Property to decide whether a < b , a = b ,     o r     a > b a) a = 12 + ( − 3 ) 9 b = 5 2 − 4 2 3 2 b) a = 2 ⋅ 3 + 4 b = 2 ⋅ ( 3 + 4 )

To determine

To decide:

Whether a<b,a=b,or a>b by using the given condition.

Explanation

Consider the following condition,

a=12+(âˆ’3)9 and b=52âˆ’4232

Trichotomy Property

If a and b are numerical expressions, then only one of the following statements can be true:

a<b,a=b,orÂ a>b

The given condition is given below,

a=12+(âˆ’3)9a=12âˆ’39<

To determine

To find:

Whether a<b,a=b,or a>b by using the given conditions.
