I don't know if this is the correct topic but i#m new here so sorry if this isn't supposed to be posted here.

So anyways iv'e been stuck on these two questions for a while now so hopefully you lot can help me out here because I really need it.

Question 1

Te^2 = M^2 + T^2 <--- Make M the subject. I would be able to

do this one but because the numbers

are squared it's confused me.

Question 2

K = sq root ((a^2 + b^2)/12) <----- Make a the subect.

Please help I need it! It would also help if you showed me your working to help me with these problems in the future.
