(-9x^(3)yz^(2))/(27x^(4)yz)=color(blue)(-z/(3x)9x3yz227x4yz=z3x

Explanation:

Simplify:

(-9x^(3)yz^(2))/(27x^(4)yz)9x3yz227x4yz

Simplify -9/27927 to -1/313.

-(x^(3)yz^(2))/(3x^(4)yz)x3yz23x4yz

Apply quotient exponent rule: a^m/a^n=a^(m-n)aman=amn.

-(x^(3-4)y^(1-1)z^(2-1))/3x34y11z213

Simplify.

-(x^(-1)y^(0)z^(1))/3x1y0z13

Apply zero exponent rule: a^0=1a0=1.

-(x^(-1)1z^(1))/3x11z13

Simplify.

-(x^(-1)z^(1))/3x1z13

Apply negative exponent rule: a^(-m)=1/a^mam=1am.

-z/(3x)z3x
