plssss answer fast

Answer 1

Let 3√7 is a rational number.

A rational number can be written in the form of p/q,

3√7 = p/q

√7 = p/3q

p,q are integers then p/3q is a rational number.

Then √7 is also a rational number.

But this contradicts the fact that √7 is an irrational number.

Therefore,our supposition is false.

So, 3√7 is an irrational number.

Hence proved.
