Answer:
the mistake is in the first statement.
Explanation:
Now lets us put the statement into consideration:
"The sum of any two rational numbers is irrational"
The negation is: " there exists a pair of rational numbers whose sum is irrational". (Existence of at least one of such a pair).
The negation is not "the sum of any two rational numbers is irrational"
Therefore the mistake is in the first statement and it is due to incorrect negation of the proof.

Explanation:
“Hexadecimal uses digits that more closely resemble our usual base-10 counting system and it's therefore easier to decide at a glance how big a number like e7 is as opposed to 11100111. Higher information density. With 2 hexadecimal digits, we can express any number from 0 to 255.”
Answer:
Written in Python
filenm = input("File name: ")
myfile = open(filenm+".txt")
for i in range(10):
line = myfile.readline()
print(line)
print("End of file")
Explanation:
This line prompts user for file name
filenm = input("File name: ")
This line creates an instance of the file
myfile = open(filenm+".txt")
This line iterates through the 10 lines
for i in range(10):
This line reads the line
line = myfile.readline()
This line prints each line
print(line)
This line prints a message indicating that all possible lines have been printed
print("End of file")
