`sqrt(-5) sqrt(-16/5)`

Evaluate the following: (i) sqrt(-25)xx(-81) (ii) sqrt(-36)xxsqrt(16) (iii) 4sqrt(-4)+5sqrt(-9)-3sqrt(-16)

The value of |{:(sqrt(13 )+ sqrt(3), 2sqrt(5),sqrt(5)),(sqrt(15) + sqrt(26),5,sqrt(10)),(3 + sqrt(65), sqrt(15),5):}|

Divide 16sqrt(75) by 5sqrt(12)

Divide 16sqrt(75) by 5sqrt(12)

Simiplify 10sqrt(5)-7sqrt(5) + 3sqrt(5)

Evaluate : sqrt(5) + sqrt(5) + sqrt(5) + sqrt (5)

(sqrt(5)-1)/(sqrt(5)+1)+(sqrt(5)+1)/(sqrt(5)-1)=a+b sqrt(5)

Evaluate : sqrt( 4 ! )/sqrt( 5! ) = ? ( A ) 5/sqrt(5) ( B ) sqrt(5) /5

The simplest rationalising factor of sqrt(3)+sqrt(5) is sqrt(3)-5( b) 3-sqrt(5)(c)sqrt(3)-sqrt(5)(d)sqrt(3)+sqrt(5)

determine a and b if (7+sqrt(5))/(7-sqrt(5))-(7-sqrt(5))/(7+sqrt(5))=a+7b sqrt(5)
