Which is greater ? 1.23 or 1.2

If A=[{:(" 1",1," 1"), (" 2",1,-3),(-1,2," 3"):}] , then M_(23)=

One mole of carbon atom weighs 12g, the number of atoms in it is equal to, ( Mass of carbon-12 is 1.9926xx10^(-23)g )

The inverse of [(1,2),(2,3)] is

1.2^(2)+2.3^(2)+3.4^(2)+

If A = [(2,3),(1,2)], B = [(1,0),(3,1)] , find AB and (AB)^(-1)
