Properties of determinants.

Question

Is this property of a determinant true?

$$|A^3| = |A|^3.$$

I haven't studied about this but while working out on a sum, wondered if this could be true, I'll check out on other sums too if this works.

Yes, that's true for any power.. – Tim May 27 '13 at 11:04 — Tim, May 27 '13 at 11:04
you could simply have checked wikipedia – May 27 '13 at 11:07 — , May 27 '13 at 11:07

Hint: use $\det(AB)=\det(A)\det(B)$.
