Show that :
`sqrt( ab ) = sqrt( a ) . sqrt( b )`

Show that : sqrt( a/b ) = sqrt(a)/ sqrt( b )

Evaluate : ( sqrt(a) + sqrt(b) ) ( sqrt(a) - sqrt(b) )

Evaluate : ( -b/a ) / sqrt( b/a ) + sqrt(b)/ sqrt(a ) = ?

Show that one value of (sqrt(i)+sqrt(-)i) is sqrt(2)

The conjugate surd of sqrt(a)+b is sqrt(a)-b b- "sqrt(a) sqrt(a)+sqrt(b) sqrt(a)-sqrt(b)

If a = (sqrt(3) - sqrt(2))/(sqrt(3) + sqrt(2)) and b = (sqrt(3) + sqrt(2))/(sqrt(3) - sqrt(2)) then value of sqrt(3a^2 - 5ab + 3b^2) is
