Hi everyone. Im new to these forums. I do Computer System Engineering at Brunel university in London. I did Maths and Physics at A-level but I'm struggling with some of the maths in my Engineering Maths module. Could someone please help me with the exam question I have attached with this post. I have searched high and low on the internet for advice or an algorithm on spotting/proving isomorphism but have failed to find a conclusive method. Any help at all would be really helpful, thanks!
