Question

pls solve question number 3

Answer 1

Answer:

Step-by-step explanation: we can write it like: (by remove the root with the power of 1/2)

$[(x^{4}y)^{3/2} * \frac{1}{(xy^{7} )^{3/2} } ]^{-4}$;

Now multiplying the power of x and y by open the brackets;

$[x^{4*\frac{3}{2} }*\frac{1}{(x\frac{3}{2} yx^{7*\frac{3}{2} } )} ]^{-4}$;

Now solving this:

$[x^{2-\frac{3}{2} }y^{\frac{3}{2}-\frac{21}{2}  }  ]^{-4}$;

$[x^{\frac{4-3}{2} }y^{\frac{3-21}{2} }  ]^{-4}$

$[x^{\frac{1}{2} }y^{-9}]^{-4}$

$x^{-2}y^{36}$
