If A [ab ba] and A² = [ln mo] then the value of l,m =?
If A [ab ba] and A² = [ln mo] then the value of l,m =?
Explanation
Given A = [a b; b a] and A² = [l m; ...], let's calculate A²:
A² = [a b; b a] * [a b; b a]
= [a² + b² 2ab; 2ab a² + b²]
Comparing A² = [l m; ...] with our calculation:
l = a² + b²
m = 2ab
The correct answer is l = a² + b², m = 2ab.
