Well then, you must spend some time learning to translate each statement. That is the first step.

For example: the statement in a) says "for any integer $$n$$, there is some integer $$m$$ such that $$n^2<m$$.
Is that true or false?

Re: quantifiers

i understand the symbols and the meaning of the statements but i want to know the answer is only true or false or i have to give counter example to express it completely

If the statement is true then say so.
If it is false then give a counter-example.

Re: quantifiers

For example: the statement in a) says "for any integer $$n$$, there is some integer $$m$$ such that $$n^2<m$$.

You'll have to think about the meaning of these statements; there is no way around it. For example, for $n=5$, can you find an integer $m$ such that $n^2=25<m$? What about for $n=0$, $n=-5$ and every other integer $n$?
