Question

Can someone double check my work?

Answer 1

2. \[(-3x^5)(2xy^4)(6xy)^0\]

I got: \[-3x^5(2xy^4) \]
\[= -6x^6y^4(1)\]
\[= -6x^6y^4\] (final answer)

Answer 2

Also,

3. \[\left(\begin{matrix}xyz^3 \\ y^5w^-7\end{matrix}\right)\]

Which I got: \[\frac{ xyz^3w^7 }{ y^5}\]

Answer 3

it looks good

Answer 4

you can subtract the y on top with bottom

Answer 5

Oops, there isn't supposed to be a parentheses for #3. And okay, so:

\[\frac{ 1}{ xy^-5z^3w^7 } \]

Answer 6

this is a new problem ?

Answer 7

Oh no, that was supposed to be the answer to the problem.

Answer 8

why did you change it ?

Answer 9

you had it right the only thing you have to do is subtract the y and you get

xz^3w^7
--------
y^4

Answer 10

Oh, okay. I had subtracted 1 from 5 and got -4 and then flipped the equation. Thank you for your help.
