Answer 1

b)ma=[5,8(3)+2,1(6)]:2
        =[583-58 supra 90 + 216-21 supra 90]:2
        =[525 supra 90+195 supra90]:2
        =720supra 90 :2
        =8:2
        =4
c)ma=[514-51supra90+857-85supra90+423-42supra90]:3
        =[463supra90+772supra90+381supra90]:3
        =1616supra90:3
        =1616supra90x1supra3
