Yes, the partition gives the two brothers equal shares.
Step-by-step explanation:
Step 1:
Assume the entire field has an area of B. So one brother takes 
, 
, and 
So we need to calculate how much this brother takes in terms of B.
To do this we calculate how much 
is.
Step 2:
To add ,
First take the LCM of the denominators 12, 6, and 4
The LCM is 12, we multiply the denominator to get the LCM value, this same value is multiplied to the numerator too.
Step 3:
One brother gets 
, so we need to calculate how much the other brother gets.
The other brother's share = 
So both the brothers get equal shares
Answer:
8a^3.
Step-by-step explanation:
(a+b)^3=a^3+b^3+3a^2b+3ab^2
(a-b)^3=a^3-b^3-3a^2b+3ab^2
(a+b)^3+(a-b)^3=2a^3+6ab^2
According to the question
(a+b)^3+(a-b)^3+6a(a^2-b^2)
Put in the value
=2a^3+6ab^2 +6a^3–6ab^2
=8a^3

Assuming the railroad network is properly constructed it would allow for the rapid transportation of large quantities of materials and troops all throughout the nation.
In the event of damage, having enough routes allows rail traffic to be rerouted around damaged rail lines. The ability to get to a location via different routes makes it harder for an enemy to cripple the rail network.
If there is only one line and it gets destroyed, all of the traffic comes to a halt.
