evaluate (1/9)^1/2

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

so would it be the same formula for 9a^{8})^{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
