Is The Square Root Of 3 A Rational Number?

Is 1 root3 a rational number?

Let 1/root3 a rational no.

=p/q where p and q are co prime integers and q not equal to 0.

then 1/root3 = p /q.

hence p×root3 is also irrational and we know that a rational no..

How do you prove that root 7 is irrational?

ie √7=p/q. we divide by the common factor to get √7 = a/b were a and b are co-prime number. that is a and b have no common factor.

Which is the smallest irrational number?

The smallest irrational number is – root2 since 3+ root2 +(-root2)= 3+root2-root2=3( a rational number).

How do you prove 3 Root 2 is irrational?

3+√2 = a/b ,where a and b are integers and b is not equal to zero .. therefore, √2 = (3b – a)/b is rational as a, b and 3 are integers.. But this contradicts the fact that √2 is irrational..
