Evaluate the derivative of the function. \( f(x)=\sin ^{-1}\left(4 x^{4}\right) \)

a) \( \left(-6 f^{2}\right)\left(2 f^{2}\right)= \) c) \( \left(7 x^{2} y^{3}\right)\left(-x y^{2}\right)= \) e) \( \left(-4 a^{2} b^{3}\right)\left(-2 a^{3} b^{2}\right) \) g) \( (3 x)(-2 x y)(-4 y)= \) i) \( (5 x)\left(2 x^{2}+3 x\right)= \)

Find the values of \( x \) and \( y \) that satisfy the equation \( 3 x+6 i=27+y i \) \( x=\square \) and \( y=\square \)

5. \( 6 \frac{3}{4} \)
