Compute: `(3!)(5!)`

Consider a binary operation * on the set {1,2,3,4,5} given by the following multiplication table (FIGURE) Compute (2*3)*4 and 2*(3*4) Is * commutative? (iii) Compute (2*3)*(4*5)

Compute: (i) (9!)/((5!)xx(3!))" " (ii) (32!)/(29!)" " (iii) ((12!)-(10!))/(9!)

Compute: 1/(5!)+1/(6!)+1/(7!)

Compute : [(4),(2),(3)]["1 0 2"]

Compute: 5/(12)-7/(12)+(11)/(12)

(i) Compute 2!+3! . Is 2!+3!=5! ? (ii) Compute (8!)/(4!) . Is (8!)/(4!)=2! ?

Compute : 2{:[(2,3,4,1),(-5,11,6,7)]:}+5{:[(11,13,-3,4),(5,-3,4,-7)]:}-6{:[(6,12,4,-2),(-3,5,11,7)]:} .

Tell what property allows you to compute (1)/(3)xx(6xx(4)/(5)) as ((1)/(3)xx6)xx(4)/(3)

Computer (i) quad (7!)/(5!) (ii) (12!)/((10!)(2!))

Compute: (18+2xx3.3)+0.003
