X=[121]arrow_forwardFinding a Coordinate Matrix In Exercises 14, find the coordinate matrix x in Rn relative to the standard basis. x=(5,2)arrow_forward
- Find the determinant of the matrix in Exercise 16 using the method of expansion by cofactors. Use a the third row and b the first column. 16. [342631478]arrow_forwardFind the determinant of the matrix in Exercise 15 using the method of expansion by cofactors. Use a the second row and b the second column. 15. [321456231]arrow_forwardProof Let A be an nn square matrix. Prove that the row vectors of A are linearly dependent if and only if the column vectors of A are linearly dependent.arrow_forward
- The determinant of a matrix product In Exercises 1-6, find (a)|A|,(b)|B|,(c)AB and (d)|AB|.Then verify that |A||B|=|AB|. A=[3443],B=[1150]arrow_forwardDetermine Whether Two Matrices Are Similar In Exercises 21-24, determine whether the matrices are similar. If they are, find a matrix P such that A=P1BP.
