a)

`sqrt(25*121*4)=sqrt25*sqrt121*sqrt4=5*11*2=110`

b)

`sqrt(strike9^1/strike16^4*strike4^1/strike81^9)=sqrt(1/36)=sqrt1/sqrt36=1/6`

c)

`sqrt8*sqrt18=sqrt(8*18)=sqrt(8*2*9)=sqrt(16*9)=sqrt16*sqrt9=4*3=12`

d)

`sqrt(8/5)*sqrt(125/2)=sqrt(strike8^4/strike5^1*strike125^25/strike2^1)=sqrt((4*25/1))=sqrt100=10`

e)

`root(3)(27/(0,008))=root(3)27/root(3)(0,008)=3/(0,2)=3:0,2=3:2/10=3*10/2=30/2=15`

f)

`root(3)11*root(3)(8/11)=root(3)(strike11^1*8/strike11^1)=root(3)8=2`

g)

`root(3)(3 3/8*0,001)=root(3)(3 3/8)*root(3)(0,001)=root(3)(27/8)*0,1=root(3)27/root(3)8*1/10=3/2*1/10=3/20`

h)

`root(3)(32*2/27)=root(3)(64/27)=root(3)64/root(3)27=4/3=1 1/3`
