What is the prime factorization of 200?<br><br> 2 2 × 5 3<br> 2 3 × 5 2<br> 2 4 × 5<br> 2 × 5 4
Misha Larkins [42]

Answer:

2^3 * 5^2

Step-by-step explanation:

We need to break 200 down into prime numbers

200 = 20*10  These are not prime

       = 4*5  * 2*5    The 4 is not prime

       = 2*2*5  * 2*5  This is prime

Rearranging

       = 2*2*2*5*5

       = 2^3 * 5^2
