(-3x^3y^4z^3)^3(2yz^2)=-54x^9y^13z^11(3x3y4z3)3(2yz2)=54x9y13z11

Explanation:

As (a^m)^n=a^((mxxn))(am)n=a(m×n) and a^mxxa^n=a^((m+n))am×an=a(m+n)

(-3x^3y^4z^3)^3(2yz^2)(3x3y4z3)3(2yz2)

= ((-3)^3x^(3xx3)y^(4xx3)z^(3xx3))(2yz^2((3)3x3×3y4×3z3×3)(2yz2

= (-27x^9y^12z^9)xx(2yz^2)(27x9y12z9)×(2yz2)

= (-27)xx2xxx^9y^(12+1)z^(9+2)(27)×2×x9y12+1z9+2

= -54x^9y^13z^1154x9y13z11
