Answer 1

Answer:

Range of R = { 8,27,125 }

Step-by-step explanation:

R = { (2,8),(3,27),(5,125) }

Range of a relation R is all the second numbers/elements in all the ordered pairs and domain is all the first elements.

•°• Range of R = { 8,27,125 }

The relation R is defined as R = {(a, a^3) : a is a prime number less than 5}.

The prime numbers less than 5 are 2, 3. Let's calculate their corresponding values for R:

For a = 2, a^3 = 2^3 = 8. So, (2, 8) belongs to R.

For a = 3, a^3 = 3^3 = 27. So, (3, 27) belongs to R.

Therefore, the range of R is the set of all second elements of the pairs in R, which is {8, 27}.
