Answer 2

Answer:

So (4-√2) (4+√2) is a rational number

Step-by-step explanation:

let z=(4-√2) (4+√2)

=4*4+4√2-4√2-√2*√2

=16-(√2)²

=16-2

=14

14 can be written as 14/1=p/q

Where p=14 and q=1

Here p and q are both ration

thus can be written in the form of p/q

So (4-√2) (4+√2) is a rational number
