Gauss elimination methoda$)$ Let Assx $=$ b be a system with unique solution. Compare the number of divisions, multiplications and additions used in solving the system using Gauss elimination and Gauss Jordan methods. Give the exact numbers and not the orders.$(3)$b$)$ Applying Gaussian elimination with and without partial pivoting and $4$ digit floating point arithmetic, solve the following system and compare the results. Show all the intermediate computations$\mathrm{.}0\mathrm{.}10631+0\mathrm{.}2122$x$2=0\mathrm{.}73810\mathrm{.}2081$z$1+0\mathrm{.}47422=0\mathrm{.}9327(1\mathrm{.}5+1\mathrm{.}5)$c$)$ Count the number of additions, multiplications and divisions required in finding matrices L and U for a matrix Asxs such that A $=$ LU$,$ using the
