0 Terminating decimals are decimals that come to an end and stop

0 ½, ¾, 7, .9876, 3.0

Perfect Squares and their roots

0 Perfect Squares have an exponent of two0 They are called perfect squares because their answers

actually create a square0 (1.4.9.16.25.36.49.64.81.100.121.144.169.196.225)0 Perfect square roots are square roots where one

number times itself will give you the answer inside the “radicand”

Irrational numbers

0 Irrational numbers are number that keep on going WITHOUT a pattern.

0 Any decimal that keeps on going in a calculator and has no pattern is irrational.

0 Any square root that is not perfect is irrational.0 Pi is irrational because it is 22/;7 or 3.1415926535…

Imperfcet square roots

0 No number multiplied by itself will ever give you the number located inside the “radicand”

0 If you do the square root of a number in a calculator and you get along decimal that has no pattern, it’s imperfect
