remember
[tex](abc)^x=(a^x)(b^x)(c^x)[/tex]
and
[tex](x^m)(x^n)=x^{m+n}[/tex]
and
[tex](x^m)^n=x^{mn}[/tex]
so
I'm going to assume that that x after the 2 exponent is multiply and not a variable to be multiplied, if it is go to option 2
[tex](5x^2y^3)^2(2x^3y^4)^3[/tex]=
[tex](5^2)((x^2)^2)((y^3)^2)(2^3)((x^3)^3)((y^4)^3)[/tex]=
[tex](25)(x^4)(y^6)(8)(x^9)(y^{12})[/tex]
[tex]200x^{13}y^{18}[/tex]

2. if that x was a variable and nod a multiply then
[tex]200x^{14}y^{18}[/tex]
