Answer:
Explanation:
#2- Like the Diagram/Chart on the top of your page says, square root of 4 is 2, which therefore is a perfect square. On the other hand… square root of 2 is going to be a lottttt of decimals, making it not a perfect square. So, answer simply put. You can tell if the square root of a number is rational or irrational by seeing if it’s a perfect square or not…….. Rational= Perfect squares ; Irrational= Not perfect squares/ squares that come out as decimals.
#4- Irrational; the numbers go on forever without having any sort of pattern to it.
#5- Irrational. If you do the square root of 25,000, you get the answer of 158.1138… etc. it doesn’t, making it not a perfect square= Irrational.
#6- This one I believe the last number you have (4.27repeating) would be Irrational; Please correct me if I’m wrong, but I think that because there’s a two in front of the 7, messing up the pattern of just continuous 7’s.
