Questions Gotten Wrong Flashcards
The first step is doing the prime factorization of this number.
The second step is to find the number of Trailing Zeros. A trailing zero is created by 5*2=10. So how many prime factors are combinations of 5&2?
Then multiply the remaining terms to find the non-trailing zero terms
You would want to split this into two triangles separated by line H.
One portion along the bottom shall be x while the other is 14-x.
Now you can use the Pythagorean theorem on the two triangles.
Another way of asking this question, is MN a multiple of 15.
Statement 1 tells us that the LCM of M and N is 80. When prime factorizing the LCM, you find all the distinct prime factors of a number.
In this case, 2^4*5. Since there are no 3s, MN will not be a multiple of 15 nor divisible by 15.
Statement 2 is insufficient.
