The greatest common factor for [tex]30x^{2}[/tex] and [tex]45x^{5}[/tex] is ____.

Answer :

Final answer:

The greatest common factor for 30x^(2) and 45x^(5) is 15x^(2).

Explanation:

To find the greatest common factor (GCF) for 30x^(2) and 45x^(5), we need to break down each term into its prime factors.

For 30x^(2), we can break it down as:

  • 30 = 2 * 3 * 5
  • x^(2) = x * x

For 45x^(5), we can break it down as:

  • 45 = 3 * 3 * 5
  • x^(5) = x * x * x * x * x

Now, let's identify the common factors:

  • Both terms have a factor of 3 and 5.
  • For the variable x, the first term has x^(2) and the second term has x^(5). The highest power of x that appears in both terms is x^(2).

Therefore, the greatest common factor for 30x^(2) and 45x^(5) is 3 * 5 * x^(2), which can be simplified as 15x^(2).
