Answer:
The correct answer is !40 cows and 28 Horses 
Step-by-step explanation:
h+5h=168
6h=168
h=168/6
h=28 horses.

<u>Part a)</u>
Given the expression

Apply exponent rule:    
 ∵
     ∵ 
Rewrite 81 as 3 · 27
Rewrite 54 as 2 · 27
                              
Factor out the common term:   27m³n
                                
      
Therefore,

<u>Part B)</u>
Given the expression

Apply exponent rule:    

Rewrite as
                                                
Factor out common term 5y²x²z
                                                 
Therefore,
