You've posted quite a lot here

Did you get anywhere with any of them?

debbieg · Answer

PEMDAS.

Eg. on the first one:

$\large -(-y)^2(y)^4$

Start with the exponents (the only one that you really need to deal with is the$\large (-y)^2$ ), then multiply left to right.

Keep in mind:
$-a^2$ is really just a factor of -1, multiplied by $a^2$, so if you have something like:

$-a^2a^5$ that is really equivalent to: $(-1)\cdot a^2\cdot a^5=-a^7$
