*** = my answer
nlexa [21]

Answer:

1. a. Our nation's founders based their new government on old ideas.

This answer is correct because all other options are merely points made but not the primary subject of the paragraph. The passage is not focused on options b, c, or d.

2. c. Our democratic republic has ancient Greek and Roman roots.

This answer seems to be correct. The passage does explain that our nation's founders based their new government ideas on old ideas that primarily came from Rome and Greece.

3. d. Government is created to serve the people.

In my opinion, this option is the correct answer. According to the passage, the citizens were the one's to elect the representatives and what not. It does not mention much of the government protecting its people or making sure they had the strongest leader. The paragraph also does not mention the government keeping countries safe from war.

Please help me with this problem
insens350 [35]
When we are talking about powers in maths, we are talking about:

'the number of times something is multiplied by itself'

For example, 2^4 is 2x2x2x2. 

Here, 2 is multiplied by itself four times, so we write it as 2^4.

Hope that helps :)
