EndersWorld:

@Shadow

Shadow:

Correct

EndersWorld:

I got 4 more if you got time

Shadow:

I have a couple minutes, fire away

EndersWorld:

\[\sqrt{50x^6}/\sqrt{2x^4}\]

EndersWorld:

\[\sqrt{25x^2}\]

EndersWorld:

Final answer is 5x

Shadow:

Correct

EndersWorld:

\[\sqrt[3]{12x^2}/\sqrt[3]{3x}\]

EndersWorld:

\[\sqrt[3]{4x}\]

EndersWorld:

\[\sqrt[3]{4x} \]<-Final answer

Shadow:

Correct

EndersWorld:

One second, gotta start a pizza for family dinner.

Shadow:

np, just had pizza myself (:

EndersWorld:

Ooo, what kind?

\[2y^4\sqrt{4x^3}\]

EndersWorld:

Final^

EndersWorld:

Nice, making Sausage Supreme

Shadow:

Missing some y

EndersWorld:

Thank you!

EndersWorld:

\[2y^4\sqrt{4x^3y^2}\]

EndersWorld:

Got 1 more

EndersWorld:

\[\sqrt[3]{54y^10}\]

Shadow:

Don't forget the 7 on y

EndersWorld:

Crap I did that wrong...

EndersWorld:

\[3y^7\sqrt{2y}\]

EndersWorld:

Still did it wrong.. I got y^9 and inside the Radical I got just y

Shadow:

Wait no you were right the first time, this is the 3rd root.

EndersWorld:

Soooo\(\color{#0cbb34}{\text{Originally Posted by}}\) @EndersWorld \[3y^3\sqrt[3]{2y}\]^Final \(\color{#0cbb34}{\text{End of Quote}}\) Is right?
