Question

please help me plzzzz its very important...​

Answer 1

Answer:

nd 3 rd ....

3) 6+√2

we have to prove 6+√2 is irrational

let us assume the opposite,

i.e, 6+√2 is rational

Hence, 6+√2 is can be written in the form of a/b

where a nd b ( b ≠ 0 ) are co- prime ( no common factor other than 1)

Hence, 6+√2 = a/b

√2 = a/b -6

√2 = a-6b /b

√2= irritational

a/b-6 = rational

Here , a/b-6 is rational number...

but √5 is irrational

since, Rational ≠ irrational

This is contradiction....

our assumption is incorrect.....

hence 6+√2 is irrational...

hence proved.....
