 1)(x^2)^4*(x^4)^3


2) (mn)^2*m^3n^4
    _____________
     m*(mn)^3

3)(a^2*a^3)^4

4) (x^2y^3)^5
    ________
    (x^2)^2*y^5

Answer 1

$rm (x^2)^4cdot (x^4)^3=x^8 cdot x^{12}=x^{20} \\ cfrac {(mn)^2m^3n^4}{mcdot (mn)^3}=cfrac {m^5n^6}{m^4n^3}=mn^3$
$rm (a^2cdot a^3)^4=(a^5)^4=a^{20} \\ cfrac {(x^2y^3)^5}{(x^2)^2cdot y^5}=cfrac {x^{10}y^{15}}{x^4y^5}=x^6y^{10}$
