let 3-√2 be a rational number

hence,

3-√2= a/ b , where a and b are integers and b is not equal to 0...

=>3-√2= a/b

=>√2= a/b -3

= >√2= a-3b/b

here a-3b/b are rational number as a and b areintegers but √2 is irrational number .

therefore , the contradiction we suppose is wrong .

hence, 3-√2 is irrational number ...
