Assuming a matrix A is row equivalent to /, and it takes 4 elementary row operations to convert A to I, then we know there exists E, E, E, and E, such that E̟E,E̟E,A=1. Therefore E,E,E,E, A=1. Use the property above to carefully solve for 4 in terms of EEE, and E. Hint, you need to use the above property four times (you need to show each step). 0 1 Let matrix A= 1 2 -1 5 8 4 Find elementary matrices that E,..E, such that E,.E, A = 1. Write your answer as such a product. Please also clearly show your work so I can see how you're finding these matrices. Use your formula from part (a) and your elementary matrices from part (b) to find the value of |A|. Reminder, calculating determinants of elementary matrices is "easy", in that you can calculate them in your head. E is either 1, -1, or k. If you used more or less than four row operations, you can simply "extend/adjust" your formula. Calculate |A| by an alternate method and make sure your answer matches what you found in part (c).
