If `sqrt(80)k=sqrt(5)` then `k=`……..

If sqrt80=ksqrt5 then k=

If (6)/(2sqrt(3)-sqrt(5))=(12sqrt(3)+6sqrt(5))/(k), then k=

a,b are distinct natural numbers that (1)/(a)+(1)/(b)=(2)/(5). If sqrt(a+b)=k sqrt(2), then the value of k is

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

If 4sqrt(3sqrt(x^(2)))=x^(k), then k=

cos66^(@)+sin84^(@)=(sqrt(15)+sqrt(3))/(k) .Then k=

cos66^(0)+sin84^(0)=(sqrt(15)+sqrt(3))/(K) then K=

sin{2(sin^(-1)(sqrt(5))/(3)-cos^(-1)(sqrt(5))/(3))}quad is equal to (k sqrt(5))/(81) then k=

If log (sqrt(2)+sqrt(3))=cosh^(-1)k then k=
