Answer 2

Given:

64

To find:

64 is a composite number or not.

Solution:

2 | 64

2 | 32

2 | 16

2 | 8

2 | 4

2 | 2

1 | 1

64 = 2 * 2 * 2 * 2 * 2 * 2 = 2 ^ 6

Since, 64 can be written as the product of primes.

Therefore, under Fundamental theorem of arithmetic, 64 is a composite number.

Conclusion:

Under, Fundamental theorem of arithmetic, 64 = 2 ^ 6 is a composite number.

Extra Information:

Fundamental theorem of arithmetic:

Every composite number can be expressed (factorised) as product of primes, and this factorization is unique apart from the order in which the primes occur.
