Which of the following shows the prime factorization of 200 using exponential notation?
Vilka [71]

Answer:

The prime factorization of 200 using exponential notation is 2^{3}\times 5^{2}.

Step-by-step explanation:

First, we decompose the number given on statement by applying prime numbers in ascending order. We see that 200 is an even number, therefore, we infer that smallest prime number within is 2.

1) \frac{200}{2} = 100 (Even number)

2) \frac{100}{2} = 50 (Even number)

3) \frac{50}{2} = 25 (Even number)

4) \frac{25}{5} = 5 (Odd number, not a multiple of 3, but a multiple of 5 since last digit is 5)

5) \frac{5}{5} = 1 (Odd number, not a multiple of 3, but a multiple of 5 since last digit is 5)

Now, we construct the prime factorization using exponential notation:

200 = 2^{3}\times 5^{2}

The prime factorization of 200 using exponential notation is 2^{3}\times 5^{2}.

Kirsten and Molly are on a 3-day bike ride. The entire route is 156 miles. On the first day they biked 64 miles, and on the seco
timama [110]
The distance that Kirsten and Molly need to bike on their third day is obtained by subtracting the sum of the distances they have traveled after two days from the length of the entire route.
 
                      distance left = 156 miles - (64 miles + 45 miles)
                                            = 47 miles
Thus, Kirsten and Molly need to bike 47 miles on their third day.
