Find the prime factorization of each composite number 45

Prime factorization means to factor the composite number into only prime numbers.
So, 45=9x5=3x3x5...which are all prime.
So your answer is 3, 3, 5

The prime factorization of  45  is   45 = 5 x  3 x  3  OR  5 ⋅ 3 ²

Step-by-step explanation:

We could also write this as:

5 ⋅ 3 ²

From the multiplication table, we know that  

45 = 5 ⋅x9  where 5  is prime, but  9  is not

 The prime factorization of  9  is  3 ⋅x3 ,

so the prime factorization of 45  is   45 = 5x 3x 3

OR

5 ⋅ 3 ²

At a constant it will take one hour to travel 32 mi.at that speed it will take 1/2 hr to travel the remaining 16 mi.it will take 1+1/2 hr to travel the 48mi @ 32mph.so 1 hr = 60 min& 1/2 hr = 30 min1+1/2 hr = 90 min.there are 60s in each 90 × 60 = 3600 seconds.the real question seriously is he why are they driving so slow? ! lol.
