Let a be the 4 x 4 matrix (20.3) considered in this lecture and the previous one. (a) determine det a from (20.5). (b) determine det a from (21.3). (c) describe how gaussian elimination with partial pivoting can be used to find the determinant of a general square matrix.

step-by-step explanation:

v,jhvljh,b.b; hk; ljujb,vuvccklokll; k,m,km,

step-by-step explanation:

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:
