Write the prime factorization of 18. Use exponents when appropriate and order the factors from least to greatest
To find the prime factorization of a number, you need to express it as a product of its prime factors. Here's how you can determine the prime factors of 18 and write its prime factorization:
Step 1: Start by dividing 18 by the smallest prime number, which is 2.
18 ÷ 2 = 9
Since 2 is a prime factor, continue with 9.
Step 2: Divide 9 by the smallest prime number, 2.
9 ÷ 2 = 4.5
Since 2 does not divide evenly into 9, move to the next prime number, which is 3.
Step 3: Divide 9 by 3.
9 ÷ 3 = 3
3 is a prime number.
Step 4: We have reached the end because 3 is a prime number. So, the prime factorization of 18 is:
18 = 2^1 × 3^2
Thus, the prime factorization of 18, with exponents when appropriate and factors in order from least to greatest, is 2^1 × 3^2.
2*9 = 2 * 3 * 3 = 2 * 3^2
Write the prime factorization of 50. Use exponents when appropriate and order the factors from least to greatest (for example, 2235).
the prime factors of 18 are:2x3x3
Write the prime factorization of 4.
Order the factors from least to greatest (for example, 2 × 2 × 3 × 5).
