See a solution process below:

Explanation:

First, use this rule of exponents to combine the x terms in the numerator and y terms in the denominator:

xa×xb=xa+b

(x4y3z2x5x5y2z2y4)3

(x4x5y3z2x5y2y4z2)3

(x4+5y3z2x5y2+4z2)3

(x45y3z2x5y6z2)3

(x1y3z2x5y6z2)3

Next, use this rule of exponents to combine the common terms:

xaxb=xab

(x1y3z2x5y6z2)3

(x15y36z22)3

(x6y3z0)3

Now, use this rule of exponents to complete the simplification:

(xa)b=xa×b

x6×3y3×3z0×3

x18y9z0

Therefore:

xr=x18r=18

ys=y9s=9

zt=z0t=0
