Answer:
1 / ( 243s^40 )
Step-by-step explanation:
For this problem, we need to know that a negative exponent simply can be rewritten in the opposing part of the fraction, for this case, the denominator.  So we can simplify as shown:
(3s^8)^-5
= 1 / (3s^8)^5
= 1 / 3^5 * s^8^5
= 1 / 243 * s^40
= 1 / ( 243s^40 )
Cheers.
 
        
             
        
        
        
The width of rectangle is  and length is
 and length is 
Step-by-step explanation:
Let, 
Width of rectangle = w
Length of rectangle = w+
Perimeter of rectangle = 
Perimeter of rectangle = 2(Length + Width) 

Subtracting  from both sides
 from both sides 

Dividing both sides by 4

Therefore, 
Width of rectangle = w =  cm
 cm 
Length of rectangle = 
The width of rectangle is  and length is
 and length is

Answer:
11/21
Step-by-step explanation:
1/3=7/21
1/7=3/21
(7+3)/21=10/21
21/21-10/21=11/21
Thus 11/21 of the circle is shaded.
 
        
             
        
        
        
There are infinite equivalent expressions. Here are some:
1/5(m-100)
20(1/100m-1)
1/5m-(4•5)
If you expand any of these or any of the terms, you will get an equivalent expression.
