Can someone show me the answer and maybe the work
Tatiana [17]

Answer:

Solving the expression \frac{y^2z^{\frac{1}{4}} }{(z^{\frac{1}{2}}.xy^{\frac{3}{2}})^3} we get \mathbf{\frac{1}{y^{\frac{5}{2} }x^3z^{\frac{5}{4} }}}

Step-by-step explanation:

We need to solve the expression:

\frac{y^2z^{\frac{1}{4}} }{(z^{\frac{1}{2}}.xy^{\frac{3}{2}})^3}

We know the exponent rule: (a^n)^m = a^{nm}

\frac{y^2z^{\frac{1}{4}} }{(z^{\frac{1}{2}}.xy^{\frac{3}{2}})^3}\\\\=\frac{y^2z^{\frac{1}{4}} }{z^{\frac{3}{2}}.x^3y^{\frac{9}{2} }}

Now, another exponent rule says that: \frac{a^m}{a^n}=a^{m-n}

=\frac{y^{2-\frac{9}{2}} z^{\frac{1}{4}-\frac{3}{2} } }{x^3}\\=\frac{y^{\frac{4-9}{2}} z^{\frac{1-3*2}{4} } }{x^3}\\=\frac{y^{\frac{-5}{2}}z^{\frac{-5}{4} } }{x^3}

We also know that: a^{-m}=\frac{1}{a^m}

=\frac{1}{y^{\frac{5}{2} }x^3z^{\frac{5}{4} }}

So, solving the expression \frac{y^2z^{\frac{1}{4}} }{(z^{\frac{1}{2}}.xy^{\frac{3}{2}})^3} we get \mathbf{\frac{1}{y^{\frac{5}{2} }x^3z^{\frac{5}{4} }}}
