the value of the det. of a matrix A of order 3x3 is 4. find the value of of |5A| Share with your friends Share 1 Varun.Rawat answered this We know that If A is a square matrix of order n, thenkA = knAso, 5A = 53A = 125 × 4 = 500 1 View Full Answer Ropienglien answered this From The property of det. We know that if a given det is multiply by a constant K ,then the new det is K times the original det Now,|A|=4 5|A|=5x4 =20 -3 Partik Rajput answered this the above mentioned solution by ropienglien is totally incorrect. here is the correct one 5A implies every element in the matrix will get multiply by 5 . now take 5 common from either each row or each column to give 5*5*5 |A| = 125|A| = 500thumbs up^^^^^^^^ 0
