Answer:
3m-3n
Step-by-step explanation:
We want to simplify the expression;
2m - [n - (m - 2n)].
We expand the parenthesis to obtain;
2m - (n - m + 2n)
2m - ( - m + 3n)
Expand further to get;
2m +m -3n
Combine the first two terms;
3m-3n

The population of Saya islands after 4 months will be 8,100 people.
It is given in the question that:-
Initial population of Saya island = 100 people
The population of the Saya island tripled every month
We have to find the population of the island after 4 months.
The population of Saya island after 1 month = 100*3 = 300 people.
The population of Saya island after 2 months = 300*3 = 900 people.
The population of Saya island after 3rd months = 900*3 = 2,700 people.
The population of Saya island after 4th months = 2700*3 = 8,100 people.
