Question

P={x:xEN,x is a multiple of 5,x^2<400}
Express this set in Roster Form or Tabular Form?​

Answer 1

Step-by-step explanation:

[x:x€N is a multiple of 5, x²<400]

given x multiple Of 5 so

when x=5 1st you will get 25

x=10 ------>100

x=15------->225

x=20-------->400

but Given x²<400 so not to consider X=20

therefore this Will Be In Roaster form As

x={25,100,225}

hope that is correct
