Can anyone help me with these questions?
1. Write as a product of their prime factors:
2. If 1080 = 2x times 3y times 5z, what are the values of x, y and z?
3. What is the only number that has no reciprocal?
4. Express 144 as the product of its factors. Write your answer in index form.
I haven't a clue and it's in for tomorrow. I'll give all of my points to whoever can supply the correct answers. Please; help if you can.
