linear algebra - Matrices and their inverses

Having a bit of an issue answering this question. The answer seems simple but I am quite unsure. I think the answer is true, as it is a true/false question. The question is:



If a square matrix B is invertible, then its inverse is also invertible - True or False? This is all the information I have. I do not know how to go about this, i've just been trying to read laws on invertible matrices but I am really confused. Going to extra classes tomorrow for it, as I said I joined the class late and now I suddenly have an assignment to hand in, so I was just looking for an answer!



Please help me out! Thanks
