Answer:

b = a/(3a-2)

Explanation:

(3a-2)^½ = (a/b)½

Square both sides

3a - 2 = a/b

Reciprocate both sides

1/(3a-2) = b/a

b = a/(3a-2)

Answer:

b =
(a)/(3a-2)

Explanation:

Given


√(3a-2) =
\sqrt{(a)/(b) }

Clear the radicals by squaring both sides

(
√(3a-2) )² = (
\sqrt{(a)/(b) } )², that is

3a - 2 =
(a)/(b) ( multiply both sides by b )

b(3a - 2) = a ← divide both sides by (3a - 2)

b =
(a)/(3a-2)
