Evaluate :

`( -b/a ) / sqrt( b/a ) + sqrt(b)/ sqrt(a ) = ?`

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

Evaluate : sqrt(a) times sqrt(b)

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

Evaluate : ( sqrt( 1 + b ) - 1) / b = a ) b /( sqrt( 1 + b ) - 1) b ) b/( sqrt( 1 + b ) + 1) c ) 1/ ( sqrt( 1 + b ) + 1)

Suppose a,b are positive real numbers such that a sqrt(a)+b sqrt(b)=183 and a sqrt(b)+b sqrt(a)=182 then find ((9)/(5))(a+b)

sqrt(a/b+b/a-2)= 1) sqrt(a/b)+sqrt(b/a) 2) sqrt(a/b)-sqrt(b/a) 3) sqrt(a)/b-b/sqrt(a) 4) sqrt(a)/b-sqrt(b)/a

(a + sqrt b)(a-sqrt b) = a^2 - b

x = ( sqrt ( a + b ) - sqrt (a -b ))/( sqrt (a +b ) + sqrt (a -b )), then what is bx ^(2) - 2ax + b equal to (b ne 0) ?

If a>b>0 are two real numbers, then the value of sqrt(a b+(a-b)sqrt(a b+(a-b)sqrt(a b+(a-b)sqrt(a b+.....)))) is
