Answer 2

Answer :

➡️ $-x^6y^7z^9$

Explanation :

→ $( 5\:/\:2 x^2 y^3 )\:×\:(-y^2 z)\:×\:( -2 x^3 y z^7 )\: ×\:( -1\:/\:5\:xyz)$

Multiply → $5x^2 y^3 / 2$ and $-zy^2$ to get

→ $-5zx^2y^5\:/\:2$

→ $-5zx^2y^5\:/\:2\:(-2yx^3z^7)\:-\:1\:/\:5\:xyz$

cancel out 2 in both numerator and denominator ,

→ $5x^{2+3}y^{5+1}z^{1+7}\:×\:( - 1\:/\:5\:xyz)$

→ $5x^5y^6z^8 ( - 1\:/\:5\:xyz)$

cancel out 5 in both numerator and denominator ,

→ $-x^6y^7z^9$
