(using the property loga (b/c) = loga b - loga c)

= loga (x^2/a^4) - loga y^3 - 4

(using the property loga (b*c) = loga b + loga c)

= loga (x^2/a^4) + loga (1/y^3) - 4

(using the property loga 1 = 0)

= loga (x^2/a^4) + loga (1/y^3) - loga a^4

(using the property loga b - loga c = loga (b/c))

= loga [(x^2/a^4) * (1/y^3) * (1/a^4)]
