Question

T = {x\x is a prime factor of 30} а​

Answer 1

Answer:

The answer is T=$\{2,3,5\}$

Step-by-step explanation:

Prime factorization of 30 is

  $30=2\times 3\times 5$

So the prime factors of 30 are 2,3 and 5

Hence

T$=\{x| \text{x is a prime factor of 30}\}$

 $=\{2,3,5\}$

(Note: 1 is not a prime factor of any natural number as 1 is not a prime number)
