Step-by-step explanation:

Answer 2

Answer:

True   ; false

Step-by-step explanation:

 i ) :

        35 = 1 * 5 * 7 * 35

   Factors of 35 are :

         1 , 5 , 7 and 35. There are only four factors of 35.

According to the given statement, x must have only four +ve factors. And in the case of 35, there are exactly four factors.

So the 35 belongs to the given set. True.

 ii ) :

       128 = 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 1 or 128 or 64 * 2 or 32 * 4  or 16 * 8 so on.

   Factors of 128 = 1, 2, 4, 8, 16, 32, 64, 128.

 Sum of factors = 255 = 1 +2 + 4 + 8 + 16+ 32 + 64 + 128

But 255 is not equal to twice of 128

Hence,

Given statement is false for 128
