HI,PLEASE MARK AS BRAINLIEST PLEASE....

Given

X= 9+4√5

√X= √ 9+4√5

= √ 2sq + (√5)sq +2.2√5

By solving inside bracket we find 9+4√5

= √(2+√5)whole sq

So √x= 2+√5

1/√x= 1/2+√5

= 1/2+√5×2-√5/2-√5

= 2-√5/4-5

= -(2-√5)

= √5 -2

Now √x - 1/√x

= 2+√5 -(√5-2)

= 2+√5-√5+2

= 4 Ans

Hope it helps.....
