Question

draw a factor tree (a)30 and (40​

Answer 1

Answer:

B) The number 40 is a composite number because 40 can be divided by 1, by itself and at least by 2 and 5. So, it is possible to draw its prime tree. The prime factorization of 40 = 23•5.

A) Every possible factor tree for the number 30 is shown below. The number 30 can be written in prime factorization as 2 x 3 x 5. All of the factors are prime numbers. Using exponential form, 30 = 213151, indicating that there is one 2, one 3 and one 5 multilplied together to get the result of 30.
