I need help

which of these numbers are irrational?
A.3
B.0.25
C.1/5 (fraction)
D.1.73205080757

A, B, and C are clearly rational numbers

In D, if you had somehow showed that the decimals do not end and do not
continue in some obvious pattern, then I could tell
It is also rational the way you showed it.

e.g. 1.73205080757.... I would classify as irrational

i mean

A.√3
and
D.√9

oh so is D classified as a irrational number bc of its pattern?

To determine which of these numbers are irrational, we need to understand the definition of an irrational number.

An irrational number is a real number that cannot be expressed as a fraction and its decimal representation goes on infinitely without repeating.

Now, let's go through each number to determine if it's irrational or not:

A. The number 3 is a rational number because it can be expressed as the fraction 3/1.

B. The number 0.25 is a rational number because it can be expressed as the fraction 1/4.

C. The number 1/5 is a rational number because it is already given in fractional form.

D. The number 1.73205080757 is an irrational number. It is the square root of 3 and cannot be expressed as a fraction. Its decimal representation goes on infinitely without repeating.

So, the only number that is irrational from the options given is D. 1.73205080757.
