Thank you for the opportunity to help you with your question!

ok it very easy you need just to know  this formule :   a^(1/2) = sqrt(a) 

so with application this formule to our exemple :

(1/9)^1/2 =   sqrt(1/9) =  sqrt(1)/sqrt(9)  and we know  sqrt(9) = 3  and sqrt(1)= 1 

so : 

(1/9)^1/2 =  1/3


Please if you don't understand just ask 

i am glad to work with you , any time you any help just invite me i will give you the best answer ok 


Good Luck 

Please let me know if you need any clarification. I'm always happy to answer your questions.

so would it be the same formula for 9a8)1/2

yes : 

9a^8)^1/2 =  (3²(a^4)²)^(1/2) =  3a^4 

now it very easy should you find it by your self
