If s and t are integers greater than 1 and each is a factor of the integer n, which of the following must be a factor of ?
1)
2) (st)²
3) s+t
a) none
b) 1 only
c) 2 only
d) 3 only
e) 1 and 2

The answer is E) 1 and 2

Step-by-step explanation:

Given that s and t are greater than 1.

Let's assume that s = 4 and t = 2 and n = 8 (each on is a factor of the integer 8)

Now check for the options -

1) ( Can be a factor of  )

2) ( Can be a factor of  )

3) ( Cannot be a factor of  )

Thus, the option is E
