Question

√23 please solve and say it is rational or irrational

​

Answer 1

Answer:

4.79583 is your answer you can even check it in your calculator

Answer 2

Step-by-step explanation:

Assume ,√23 is a rational no.

√23 = a/b, 

where a, b are integers, 

sqaring both sides,

therefore 23 = a²/b². 

So a² = 23b². 

Now √a² = a = an integer, 

and 

therefore √23b² = integer. 

√23b²= b*√23

√23 is not an integer,  so the assumption was wrong. 

Therefore √23 is not rational.

Sorry for the mistake I done before this

Hope it helps u....
