Answer 2

what do i do with these lol

Answer 3

An inverse matrix multiplied by the original matrix would leave you with the identity matrix... like 1 0 0 0 1 0 0 0 1 for the 3 rows.

(Sorta like the inverse of a number like 8 is 1/8 since you multiply to get the identity element for multiplication.... remember that way back in Algebra 1?)

Answer 4

I don't know exactly what process you would use, but since the second row here is all zeros, I can't imagine any way you could think of a matrix that you could multiply times this one that would yield the identity.

Sort of like the number 0 has no inverse... nothing you can multiply it by to give you 1.

Answer 5

so there is no inverse

Answer 6

that's what I'm thinking... (turns out I need to review logarithms AND matrices!!!)

Answer 7
