Everytime I try this with exponential it ends up being really messy and no doubt I'm cancelling something wrong or something similar. Is the exponential the only way to do it?
Same as above, my exponentials just get hugely messy..
Write as an algebraic expression in x.
Is the only way to do this with the exponentials [do I have to use the answer above]? If so, same as the two above.
Thanks in advance,
