Answer:


x^(27)y^(24)z^(51)

Explanation:


\left(((x^3yz^4)^2(xy^2z^3)^4)/(xy^2z^3)\right)^3=x^(3(3\cdot 2+1\cdot 4-1))y^(3(1\cdot 2+2\cdot 4-2))z^(3(4\cdot 2+3\cdot 4-3))\\\\=x^(3(6+4-1))y^(3(2+8-2))z^(3(8+12-3))=x^(27)y^(24)z^(51)

_____

You can recognize that the denominator factor is also one of the numerator factors, so can be cancelled right away. Proceeding to evaluate inside parentheses first, we get ...


\left(((x^3yz^4)^2(xy^2z^3)^4)/(xy^2z^3)\right)^3=\left((x^3yz^4)^2(xy^2z^3)^3\right)^3\\\\=(x^6y^2z^8x^3y^6z^9)^3=(x^9y^8z^(17))^3\\\\=x^(27)y^(24)z^(51)

_____

The rules of exponents that apply are ...


(a^b)(a^c)=a^(b+c)\\\\(a^b)^c=a^(b\cdot c)
