Weba2+2a+1 = (a+1)2 then, according to the law of transitivity, (a+1)2 = 0 We'll refer to this Equation as Eq. #4.2.1 The Square Root Principle says that When two things are equal, their square roots are equal. Note that the square root of (a+1)2 is (a+1)2/2 = (a+1)1 = a+1 Now, applying the Square Root Principle to Eq. #4.2.1 we get: a+1 = √ 0 WebIf E is of type III, then ET is also of type III; so det ET =1 =det E by Theorem 3.1.2. Hence, det ET =det E for every elementary matrix E. Now let A be any square matrix. If A is not invertible, then neither is AT; so det AT =0 =det A by Theorem 3.2.2. On the other hand, if A is invertible, then A =Ek···E2E1, where the Ei are elementary ip geolocation with map
