If x=3+2√2, what is the value of √x -1/√x?

এখানে ,
x =3 +2√2
বা,x=2+2√2+1
বা,x=(√2)²+2√2+(1))²
বা,x=(√2+1)²

অতএব , 1/√x =1/(√2+1)
                       =(√2-1)/(√2+1)(√2-1)
                        =(√2-1)/(√2)² -(1))²
                         =(√2-1)/2-1
                        =(√2-1)/1
                        =(√2-1)
অতএব ,√x -1/√x  = √2+1 -(√2-1)
                              =√2+1 -√2-1
                               =2
