Simplify or multiply each of the following expressions as appropriate.

1. $(3x^2yz^4 )^2$

$9x^4y^2z^8$

1. $( \frac { r ^ { 2 } s } { r s ^ { 3 } t } ) ^ { 3 }$

Simplify inside the parentheses first, then cube.

$\frac{r^3}{s^{6}t^{3}}$

1. $(3m + 7)(2m - 1)$

$6m^² + 11m - 7$

1. $(x - 3)^2$

$x^2 - 6x + 9$
