Question

If a is a square matrix with a =8 then find the value of aa'

Answer 1

if a is square matrix with |a| = 8 then value of |aa'| = 64

if a is square matrix with |a| = 8 then find the value of |aa'|

we know, value of determinant of a matrix and that of transpose are same.

I.e., |a| = |a'|

or, |a||a'| = |a'||a'| = |aa'|

or, |aa'| = |a'|² = |a|² = (8)² = 64

hence, value of |aa'| = 64
