Question

let a and b integers. by the law of contrapositive prove if ab even then either a is even b is even :​

Answer 1

Step-by-step explanation:

Given let a and b integers. by the law of contrapositive prove if ab even then either a is even b is even :

• Now a and b are integers.
• Now we have contrapositive (if not q then not p)
• that if p then q it is negation q  negation p
• Suppose consider a is even and b is also even then ab will be even.
• Suppose consider a is odd and b is also odd then ab will be odd
• Suppose consider a is even and b is odd then ab will be even
• Suppose consider a is odd and b is even then ab will be even
• Now suppose a statement is made
• If a and b is odd then ab is odd
• So a and b will be p and ab will be q This will be p implies q
• Contrapositive will be negation q implies negation p
• Therefore if ab is even then either a is even or b is even
