Answer:
1- 5xy³√5y
2- 2xy²∛3y²
Step-by-step explanation:
√125x²y^7=
√25*5x²y^6y
5xy³√5y
2) ∛24x³y^8=
∛2³*3x³y^8=
2xy²∛3y²
Answer:
A) S,T,R
Step-by-step explanation:
let the other leg be x cm.
(5)^2+(x)^2=(12)
25+(x)^2=144
(x)^2=144-25
x=√119
x=10.9
IT IS 6 2/3 BECAUSE 6 GOES INTO 40 6 TIMES WITH A REMAINDER OF 4. SO, IT IS 6 4/6. YOU GOT TO SIMPLY SO IT IS 6 2/3
Simple....
you have:

So...first you know you're trying to find x..
But, you have a square root on one side...to remove this you'd have to square both sides--->>>

Leaving you with....

Move the terms over and set it equal to
zero.
-->>

Factor out a 3...

What multiplies to -12 and adds to 4?
6*-2=-12
6+-2=4
Leaving you with...

Remember you're solving for 0....
3x-2=0
3x-2=0
+2 +2
3x=2

x=
Then-->>
x+2=0
x+2=0
-2 -2
x=-2
Thus, your answer.
