Determine the prime factorization of 36. 62 22 · 9 22 · 32 4 · 9

larisa [96]

ANSWER
The prime factorization of 36 is
${2}^{2} \times {3}^{2}$

EXPLANATION

We want to find the prime factorization of 36.

The prime numbers that are factors of 36 are
$2 \: and \: 3$

So we find the number of times these two prime factors will multiply to get 36.

Thus,

$36 = 2 \times 2 \times 3 \times 3$

Thus gives
$36 = {2}^{2} \times {3}^{2}$
