Given:

Consider the given expression is:


(x^4y^(-4)z^(-2))/(x^2y^(-2)z^4)

To find:

The simplified form of the given expression.

Solution:

We have,


(x^4y^(-4)z^(-2))/(x^2y^(-2)z^4)

By using the quotient property of exponents, we get


=x^(4-2)y^(-4-(-2))z^(-2-4)
\left[\because (a^m)/(a^n)=a^(m-n)\right]


=x^(2)y^(-4+2)z^(-6)


=x^(2)y^(-2)z^(-6)

By using negative exponent property, we get


=(x^(2))/(y^(2)z^(6))
\left[\because a^(-n)=(1)/(a^n)\right]

The simplified form of the given expression is
(x^(2))/(y^(2)z^(6)).

Therefore, the correct option is B.
