It's 1 and 7/9

√[1/7/9] = [1/(7/9)] = √[9/7] = ±3/√7

Wait a sec. Is it 1/(7/9)? or (1/7)/9? Well, here's both cases:

[1/(7/9)]^(1/2)
= [1*(9/7)]^(1/2)
= (9/7)^(1/2)
= √(9/7)
= ±3/(√7)
= ±(3√7)/7

[(1/7)/9]^(1/2)
= [1/63]^(1/2)
= √(1/63)
= ±1/(3√7)
= ±(√7)/21

1/7/9 is the same as (1/7)/9 (order of operations), so I won't write it out again.

(16/9)^(1/2) = 4 / 3

1/7/9=1/(7*9)
so
(1/(9*7))^1/2= 1/[(9^1/2)*(7^1/2)]=1/(3*sqrt7)
=sqrt7/21
