1)

$3x {}^{2} y \times ( - 5)xy {}^{2}$

$- 15x {}^{3} y {}^{3}$

2)

$- 5xyz \times (3x {}^{2} )$

$- 5xyz \times 3x {}^{2}$

$- 15x {}^{3} yz$

3)

$4x \times ( - 5x {}^{2} y {}^{3} z)$

$- 20x {}^{3} y {}^{3} z$

4)

$- 5x \times (3y {}^{2} z)$

$- 5x \times 3y {}^{2} z$

$- 15xy {}^{2} z$

5)

$15x {}^{2} y {}^{2} \div ( - 3) \times x$

$- 5x {}^{2} y {}^{2} x$

$- 5x {}^{3} y {}^{2}$

6)

$- 14x {}^{3}y {}^{3} z {}^{4} \div 7xyz {}^{2}$

7)

$(5x {}^{2} ) {}^{2}$

$5 {}^{2} \times (x {}^{2} ) {}^{2}$

$25x {}^{4}$

8)

$( - 3xy {}^{2} ) {}^{3}$

$( - 3) {}^{3 } \times x {}^{3} \times (y {}^{2} ) {}^{3}$

$- 27x {}^{3} \times (y {}^{6} )$

9)

$(3x {}^{3} y {}^{5} ) {}^{2}$

$3 {}^{2} \times (x {}^{3} ) {}^{2} \times (y {}^{5} ) {}^{2}$

$9x {}^{6} y {}^{10}$
