To determine

To Find:which number is not a prime factor of 90.

F.2

G.3

H.5

I. 9

Answer to Problem 46STP

I. 9

Explanation of Solution

Given information:

The prime factorization of $12x^3{y}^2$ isB. $2\cdot 2\cdot 3\cdot x\cdot x\cdot x\cdot y\cdot y$

Calculation:

From the graph, the age of boa constrictor is 30

Factor tree of 90:

  

The prime factorization of 90 is $2\cdot 3\cdot 3\cdot 5$

Therefore I.9 is not a prime factor of 90.
