OpenStudy (tyrenhere):

!!

OpenStudy (tyrenhere):

Uhmmm. What grade is this?

alones (alones):

Tyren just help >.> @MissSmartiez so what choice you pick for number 1? or you need that explained?

OpenStudy (misssmartiez):

Back, and yes, I do need assistance on number one.

OpenStudy (misssmartiez):

and two))

alones (alones):

Well \[\frac{ 36 }{ 6 }\] is what?

OpenStudy (misssmartiez):

6

alones (alones):

Right 6, but now you see that it's -36 so 6 would be negative 6 you get this?

OpenStudy (misssmartiez):

Oh, I see, is that how you find out what a negative square root number is?

alones (alones):

That should be

OpenStudy (misssmartiez):

Alright, how about number two? Is it D?

alones (alones):

OKay it's kinda blury for me does it say \[x^3?\]

OpenStudy (misssmartiez):

Correct.

OpenStudy (misssmartiez):

It does.

jhonyy9 (jhonyy9):

D. not is right

alones (alones):

No the answer should be C since just factor by using difference of cubes and set each factor that would equal to 0.

jhonyy9 (jhonyy9):

bc. -5^3 = -125 and there is +125

OpenStudy (misssmartiez):

Oh. My lesson says: Square Root: If a^2 = b, then a = ±(square root)b So it only goes with ^2?

jhonyy9 (jhonyy9):

but you wrote there radical index 3

OpenStudy (misssmartiez):

I was confused on C and D, so I figured it was D because of the tip. So, it only goes for (x^2) <---

OpenStudy (misssmartiez):

I know. Thats why I said, it only goes for ^2 and not ^(anything but two)

OpenStudy (misssmartiez):

?

jhonyy9 (jhonyy9):

but there on this exercise posted wrote x^3 = 125/27

OpenStudy (misssmartiez):

I know. My lesson said a^2 = +/-, and I figured if any a^(any exponent number) would equal +/-, so I was confused and asked if thats what it was referring to. I made a mistake. It only works for ^2.

jhonyy9 (jhonyy9):

yes this is right just for a^2 bc for example sqrt9 = +/- 3 bc. 3*3=9 and -3 *(-3) = +9 too ok. ?

OpenStudy (misssmartiez):

Alright, thank you.
