The Brainliest Answer!
At first the given number should be assumed as rational number
-We know rational number form is a/b where a,b are co-primes and a not equal to 0
-Next cross multiply them
-Then Square on both sides if there are two root vales given or else just take LCM if only one root
-Then put root vale one side and normal vales one side
-On the whole at last u get Irrational number(root num)=Rational number

-But irrational num is not equal to rational number
-Our assumption is wrong,SO given NUMBER IS IRRATIONAL

IF any doubts plz say ill help u with an example
