Let `R={(a ,\ a^3): a` is a prime number less than 5} be a relation. Find the range of `R` .

Answer

Range `={8,27}`

Explanation

Given,


`R={(a, a^{3})` : a is a prime number less than 5}


for `a=1 , a^3 =1 `

all the condition are satisfied but a=1 is not a prime

`therefore a=1 notin R`


for `a=2 , a^3 =8 `

`therefore a=2 in R`

for `a=3 , a^3 =27 `
