  2. How many factors are there in 900 and how did you find that using the rule you taught me about counting factors in the instruction unit plz advice

    1. Start by taking the prime factorization of 900. We know 900 is a perfect square, 900 = 30 x30, so it will have an odd number of factors.
      900 = 30 x 30 = (6 x 5) x (6 x 5) = (2 x 3 x 5) x (2 x 3 x 5) = (2 x 2) x (3 x 3) x (5 x 5) = 223252
      There are 3 prime factors; 2, 3, and 5. Each one is raised to the power of 2 or squared.
      Recall the rule to count the factors is to add 1 to the power of each prime factor and multiply them all out. In this case that is,
      (2+1) x (2+1) x (2+1) = 3 x 3 x 3 = 27 factors including 1 and the number itself.

  3. I don’t really understand number 38. I can get as far as finding the rate(8), but then I don’t really understand what is happening after that point.
