Simplify the following:

(abc)^4*(4b)^-2*(3a)^3

Am I correct in assuming that (abc)^4 is equal to a^4*b^4*c^4?

[(a^4*b^4*c^4)*(3a)^3]/(4b)^2
[(a^4*b^4*c^4)*27a^3]/[16b^2]
[27*a^7*b^4*c^4]/[16*b^2]
[27*a^7*b^2*c^4]/16

Is this all correct? Is it completely simplified? Please help.

Simplify the following:

(abc)4×(4b)2×(3a)3\displaystyle (abc)^4\times(4b)^{-2}\times(3a)^3

Am I correct in assuming that (abc)4\displaystyle (abc)^4 is equal to a4×b4×c4\displaystyle a^4\times b^4\times c^4? ... That's a fact!

(a4b4c4)(3a)3(4b)2\displaystyle \frac{(a^4b^4c^4)(3a)^3}{(4b)^2}

(a4b4c4)27a316b2\displaystyle \frac{(a^4b^4c^4)27a^3}{16b^2}

27a7b4c416b2\displaystyle \frac{27a^7b^4c^4}{16b^2}

27a7b2c416\displaystyle \frac{27a^7b^2c^4}{16}

Is this all correct? Is it completely simplified? ... looks perfect to me, impressive work!
