Answer: Choice A) 2^2*3^2*5
========================================================
Step-by-step explanation:
To find the prime factorization, we'll start by dividing 180 by the smallest prime number
Divide 180 by 2 to get 180/2 = 90
Divide that by 2 to get 90/2 = 45
Then note how 45/2 = 22.5 isn't a whole number, so that means we move onto the next prime number 3
45/3 = 15
15/3 = 5
The denominators we used, in order, were: 2, 2, 3, 3
This means that 2*2*3*3 is part of the factorization. We can condense that to 2^2*3^2
The last term 5 is the final missing piece of the factor puzzle
Meaning, 2^2*3^2*5 = 180
I recommend you use a calculator to confirm this.
