3:a 4:b 
Step-by-step explanation:
 if 5^2 x 5^4 you add the exponents so then it would be 5^6
 
        
                    
             
        
        
        
Answer:
The change to the face 3 affects the value of P(Odd Number)
Step-by-step explanation:
Analysing the question one statement at a time.
Before the face with 3 is loaded to be twice likely to come up.
The sample space is:

And the probability of each is:








P(Odd Number) is then calculated as:


Take LCM



After the face with 3 is loaded to be twice likely to come up.
The sample space becomes:

The probability of each is:








Take LCM


Comparing P(Odd Number) before and after
 --- Before
 --- Before
 --- After
 --- After
<em>We can conclude that the change to the face 3 affects the value of P(Odd Number)</em>

Answer:
a  4 1/5
b  7 7/24
Step-by-step explanation:
a  7/9 * 5 2/5
Change the mixed number to an improper fraction
7/9 * (5*5+2)/5
7/9 * 27/5
Rewrite 
 7/5 * 27/9
 7/5 * 3 
21/5
Change this back to a mixed number
5 goes into 21 4 times  (4*5 = 20 ) with 1 left over
4 1/5
b  1 3/4 * 4 1/6
Change to improper fractions
(4*1+3)/4  * (6*4+1)/6
7/4 * 25/6
175/24
Change back to a mixed number
24 goes into 175 7 times  (7*24 =168 ) with 7 left over
7 7/24
