" 18.Show that "3sqrt(45)-sqrt(125)+sqrt(200)-sqrt(50)=4sqrt(5)+5sqrt(2)

sqrt(45)-3sqrt(20)+4sqrt(5)

Simplify: 3sqrt(45)-sqrt(125)+sqrt(200)-sqrt(50) .

8sqrt(5)+sqrt(20)-sqrt(125)

sqrt5 sqrt(-125)=

3sqrt(4)+2sqrt(9)+5sqrt(4)-sqrt(1)-4sqrt(9)

Simplify (i) 3 sqrt ( 45) - sqrt (125) + sqrt (200) - sqrt(50) (ii) ( 2 sqrt ( 30 ))/( sqrt ( 6)) - ( 3 sqrt(140))/(sqrt ( 28)) + (sqrt(55))/(sqrt(99)) (iii) sqrt (72) + sqrt(800) - sqrt ( 18 )

If 3sqrt(5)+sqrt(125)=17.84 then sqrt(80)+6sqrt(5)=

Show that (1)/(sqrt(2)+sqrt(3))-(2)/(sqrt(5)-sqrt(3))+(3)/(sqrt(5)-sqrt(2))=0 .

show that (sqrt(7)-sqrt(5))/(sqrt(7)+sqrt(5))times(sqrt(7)-sqrt(5))/(sqrt(7)-sqrt(5)) =frac{(sqrt(7)-sqrt(5))^(2)}{2}
