Hey, thanks for your help.

i am unsure of #1, but #2 is correct, i beleive. i am also a student and though i am not positive, i have worked the problem several times and am fairly certain this is the correct answer.

The answer is B because all factors in 5^3 x 7^2 x 19^2 are prime. For example, 5,7,19, 3 and 2 cannot be decomposed. An example of decomposed is 9 where it can be divided by a number other than 1 and the number itself.

The answer is .45 T F = B(I)L B = F/(I)L B = .90/4(.5) B = .45 T (T is Teslas)
