1] 8^(2n - 3) . 2^(n - 3) / (4 . 2^(2 - n))
= 2^(3(2n - 3)) . 2^(n - 3) . 2^(-2) . 2^(-2 + n)
= 2^(6n - 9 + n - 3 - 2 - 2 + n)
= 2^(8n - 16)

2] (p^2 q^3)^4 : (p^3 q^3)^2
= (p^(2 x 4) . q^(3 x 4) : (p^(3 x 2) . q^(3 x 2))
= p^(8 - 6) . q^(12 - 6)
= p^2 . q^6

3] (4a^-4/b^2)^(-1/2)
= 2^(2 x -1/2) . a^(-4 x -1/2) . b^(-2 x -1/2)
= 2^-1 . a^2 . b^1
= a² . b/2
