Question

Solve the following
1. R = {m|m€i,m^3 = 27}
2. S = {n|n^2 -25=0}​

Answer 1

Step-by-step explanation:

a). Answers:- R = {m|m€i,m^3 = 27}

m³ = 27

⇒ m³ = 3³

⇒ m = 3

So,R = { 3 }

Number of elements in the set R = n{R} = 1 ..

Therefore,it's a singleton set..

b).Answers :- S = {n|n^2 -25=0}
