sqrt(16)-sqrt(5)

Express each one of the following with rational denominator: (1)/(3+sqrt(2))( ii) (1)/(sqrt(6)-sqrt(5))( iii) (16)/(sqrt(41)-5)

If a=sqrt(17)-sqrt(16) and b=sqrt(16)-sqrt(15) then

(sqrt(12)+sqrt(5)+sqrt(3))/(sqrt(12)-sqrt(5)-sqrt(3))+(sqrt(20)+sqrt(5)+sqrt(3))/(sqrt(20)-sqrt(5)-sqrt(3))

Express each one of the following with rational denominator: (i) 1/(3+\ sqrt(2)) (ii) 1/(sqrt(6)-\ sqrt(5)) (iii) (16)/(sqrt(41)-\ 5)

Simplify : 3sqrt(-16)-2sqrt(-9)+4sqrt(-36)

Find the value of root3(sqrt(441)+sqrt(16)+sqrt(4))

Simplify : 3sqrt(-16)-2sqrt(-9)+4sqrt(-36)

(sqrt(5)-sqrt(5))/(sqrt(5)-sqrt(5))

Evaluate sqrt(16)+sqrt((9.5xx0.0085xx18.9)/(0.021xx0.0017xx1.9)) .

If (sqrt(5 + 2sqrt6)- sqrt(5 - 2 sqrt6))/(sqrt(5 + 2 sqrt6)+ sqrt(5 - 2 sqrt6)) = sqrt((x)/(16)) , then x = _____
