Answer 1

Answer:

Hope its helps u  YO :)

Step-by-step explanation:

1- To prove :- 4√2 is an irrational number .

So let us assume that 4√2 is a Rational Number .

4√2 = r

√2 = r/4

Now, we know √2 is an irrational number.

So RHS { r/4 } cannot be rational . As then the equation will be false .

So our Assumption is Wrong .

2- Do same same sa first one

>root5=p/q-3

​=>root 5=p-3q/q

as p, q and 3 are integers p-3q/3 is a rational number.

=>root 5 is a rational number.
