Do you have a calculator handy? If you do you can plug in sqrt(42) to see what that looks like.
jtvatsim
  • jtvatsim
As a long way to the answer, here's what I am thinking:
jtvatsim
  • jtvatsim
rational numbers are fractions... No way is sqrt(42) a fraction, it's decimals don't repeat.
Phebe
  • Phebe
yes i have a calculater
jtvatsim
  • jtvatsim
Because it's decimals don't repeat it is an irrational number for sure.
jtvatsim
  • jtvatsim
Whole numbers are like 1, 2, 3, 4, and have no decimals.... so no to that.
jtvatsim
  • jtvatsim
Integers are just whole numbers that are 0 or negative too, so -2, -1, 0, 1, 2, ... so no
jtvatsim
  • jtvatsim
So, in other words, I think the answer is B. This is an irrational number because the decimals don't repeat.

Yep, what a mess... definitely not a nice whole number, natural number, or integer.
Phebe
  • Phebe

jtvatsim
  • jtvatsim
It is an irrational number. B Irrationals have nonrepeating decimals.
