Will give medal

@ZeHanz can you help im super lost

zehanz · Answer

I think your expression is:

$(-2x^{8})\cdot 3y^{9}\cdot 2x^{4}$.

You can rearrange the factors:

$-2\cdot 3\cdot 2\cdot x^{8}\cdot x^{4}\cdot y^{9}$

Now use the power rule $x^{n}\cdot x^{m}=x^{n+m}$.
Can you do that?

anonymous · Answer

I think so but i can see the numbers to the power it looks like x^72*x^192=x^72+m are those the right numbers?

anonymous · Answer

would the answer be   1.5x10^12?

zehanz · Answer

That doesn't make sense.
1.5x10^12 = 1,500,000,000,000, so that is just a very large number.
In the expression you gave, there are x's and y's.
After simplifying the expression, there will still be x's and y's.

My answer would be: $-12x^{12}y^{9}$

mmmm thats true but all of my answer choices dont come close to yours?

zehanz · Answer

Can you show a picture of the expression, to be sure what it is?
