$x^{\frac{13}{2}} y^{- 2} z^{9} + x^{4} y^{5} z^{7}$ $x^(13/2)y^-2z^9+x^4y^5z^7$

From the given expression $(\sqrt{x^{- 5}} + x^{- 5} y^{7} z^{- 2}) (x^{9} y^{- 2} z^{9})$ $(sqrt(x^-5)+x^-5y^7z^-2)(x^9y^-2z^9)$

Get the product

$(\sqrt{x^{- 5}} + x^{- 5} y^{7} z^{- 2}) (x^{9} y^{- 2} z^{9})$ $(sqrt(x^-5)+x^-5y^7z^-2)(x^9y^-2z^9)$

$(x^{- \frac{5}{2}} + x^{- 5} y^{7} z^{- 2}) (x^{9} y^{- 2} z^{9})$ $(x^(-5/2)+x^-5y^7z^-2)(x^9y^-2z^9)$

$x^{- \frac{5}{2}} \cdot (x^{9} y^{- 2} z^{9}) + (x^{- 5} y^{7} z^{- 2}) (x^{9} y^{- 2} z^{9})$ $x^(-5/2)*(x^9y^-2z^9)+(x^-5y^7z^-2)(x^9y^-2z^9)$

$x^{- \frac{5}{2} + 9} \cdot (y^{- 2} z^{9}) + (x^{9 - 5} y^{7 - 2} z^{9 - 2})$ $x^(-5/2+9)*(y^-2z^9)+(x^(9-5)y^(7-2)z^(9-2))$

$x^{\frac{13}{2}} y^{- 2} z^{9} + x^{4} y^{5} z^{7}$ $x^(13/2)y^-2z^9+x^4y^5z^7$

God bless....I hope the explanation is useful.
