Question

PLS HELP EMERGENCY Select the BEST classification for the square root of 27 . A) irrational B) rational C) imaginary D) complex E) natural

Answer 1

Answer:

A) Irrational

Step-by-step explanation:

The square root of 27 is an irrational number since it's not a rational number. We identify rational numbers because they can be expressed as fractions

If we take the value of $\sqrt{27}$ we get

5.1961524227066318805823390245176...

There is no way to transform that number into a fraction because

* It has no decimal limit

* It has no decimal pattern (or period)

Examples of rationals are

5.44444...

$0.\overline{32}$

2.375

The last one has limited decimals, the first two have repetitive patterns or a period.
