Question

if A×B=A^2-B^2 and AyB=A^2+B^2 then,(9×6)y(8×5)=?​

Answer 1

Answer:

3546

Explanation:

A×B=A^2-B^2 ...eq1

On this equation 1

A1 and B1 = 9 and 8 respectively

A2 and B2 = 6 and 5 respectively

Then we get

(9×6) = 9^2 - 6^2

= 81 - 36

= 45

similarly, (8×5) = 8^2 - 5^2

= 64 - 25

= 39

Hence, we get 45 and 39

AyB=A^2+B^2 ...eq2

On this equation 2

A = 45 and B = 39

Putting in eq2 we get

45 y 39 = 45^2 + 39^2

= 3546

Thank you.
