Which decimals are irrational numbers? Select two answers. A. π π B. 1 1 3 113 C. 8 526 8526 D. 0 . 212212221 … 0.212212221… E. 5 9
I think C
i give you a hint and you will be the superman of that question
a rational numbers are numbers that are reoccurring,which can be express as a fraction
so now begin the elimination process
b and e?
is (e) 5.9?
i don't know where you getting those answers
all of your answers are rational....
integers are rational
non-terminating decimals with repeating digits are rational
anything else is irrational
5/9
To determine which decimals are irrational numbers, we need to recall what an irrational number is. An irrational number is a number that cannot be expressed as a fraction of two integers and does not terminate or repeat infinitely.
Let's evaluate each option:
A. π (pi): π is an irrational number because it cannot be expressed as a fraction and its decimal representation goes on forever without repeating. Therefore, A. π is an irrational number.
B. 1 1 3 113: 113 is a rational number because it can be expressed as a fraction (113/1) and terminates. Therefore, B. 1 1 3 113 is not an irrational number.
C. 8 526 8526: 8,526,8526 is a rational number because it can be expressed as a fraction (8,526,8526/1) and terminates. Therefore, C. 8 526 8526 is not an irrational number.
D. 0 . 212212221 … 0.212212221…: This decimal representation does not terminate or repeat, indicating that it is non-repeating. Therefore, D. 0 . 212212221 … 0.212212221… is an irrational number.
E. 5 9: 5/9 is a rational number because it can be expressed as a fraction. Therefore, E. 5 9 is not an irrational number.
From the given options, the two decimals that are irrational numbers are A. π and D. 0 . 212212221 … 0.212212221….
