Problems from Operations with monomials

Development:

1. $(3\cdot 5)\cdot (xy\cdot xyz)$
2. ${\displaystyle \frac{5}{3}}\cdot {\displaystyle \frac{z^{5}x}{z^3{x}^2}}={\displaystyle \frac{5}{3}}\cdot {\displaystyle \frac{z^5}{z^3}}\cdot {\displaystyle \frac{x}{x^2}}$
3. $(-3{)}^5\cdot (x^2{)}^5=-3^5\cdot x^{1}0$

Solution:

1. $15x^2{y}^{2}z$
2. ${\displaystyle \frac{5}{3}}{\displaystyle \frac{z^2}{x}}$
3. $-243x^{1}0$
