4. 2 points] Given the matrix ai a2 a,3 LC 2 Cs and the matrix B is obtained from matrix A by performing elementary row opera- tions such that: B- m.ai m.a2 m.a3 k.ci k.c2 k.cs Where, and k and non-zero constants. Let Al be known. Calculate IBI as a function of IAl using properties of determinants. Show all your steps! Note: There is no need to perform Laplace expansion. Simply keep |Al as it is and write IBl in terms of IAl (so your final answer is: B (some constant)IAl)
