8. If A= {2, 4} and B = {4, 2}, Can we write A×B = A2 and B×A= B2 ? - Advance Math Class 10 - Exercise: 1.2
Given, A= {2, 4} and B = {4, 2}
⇒Now,
⇒A×B = {2, 4} × {4, 2}
= {(2, 4), (2, 2), (4, 4), (4, 2)}
⇒
= {2, 4} × {2, 4}
= {(2, 2), (2, 4), (4, 2), (4, 4)}
⇒ And,
⇒ B×A = {4, 2} × {2, 4}
= {(4, 2), (4, 4), (2, 2), (2, 4)}
⇒
= {4, 2} × {4, 2}B
= {(4, 4), (4, 2), (2, 4), (2, 2)}
Therefore, A×B =
and B×A= ![8. If A= {2, 4} and B = {4, 2}, Can we write A×B = A2 and B×A= B2 ? - Advance Math Class 10 - Exercise: 1.2 8. If A= {2, 4} and B = {4, 2}, Can we write A×B = A2 and B×A= B2 ? - Advance Math Class 10 - Exercise: 1.2](https://latex.codecogs.com/gif.image?\large&space;\dpi{120}B^{2})
