Answer:
c)The proof writer mentally assumed the conclusion. He wrote "suppose n is an arbitrary integer", but was really thinking "suppose n is an arbitrary integer, and suppose that for this n, there exists an integer k that satisfies n < k < n+2." Under those assumptions, it follows indeed that k must be n + 1, which justifies the word "therefore": but of course assuming the conclusion destroyed the validity of the proof.
Step-by-step explanation:
when we claim something as a hypothesis we can only conclude with therefore at the end of the proof. so assuming the conclusion nulify the proof from the beginning
Answer:
the value of x-1/x is given down
Step-by-step explanation:
=(x+1/x)²=x²+1/x²+2
=(5)²=x²+1/x²+2
=x²+1/x²=25-2
=x²+1/x²=23 this is the answer
if u ask there how 25 came means there (5)² is that u should multiply 5×5 and u will get 25bas the answer
