Expression equivalent to 
is ![(\sqrt[d]{3b})^2](https://tex.z-dn.net/?f=%28%5Csqrt%5Bd%5D%7B3b%7D%29%5E2)
Option D is correct.
Step-by-step explanation:
We need to find equivalent expression of:
Solving:
We know that ![\frac{1}{d}= \sqrt[d]{}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7Bd%7D%3D%20%5Csqrt%5Bd%5D%7B%7D)
So, the expression will become:
![=(\sqrt[d]{3b})^2](https://tex.z-dn.net/?f=%3D%28%5Csqrt%5Bd%5D%7B3b%7D%29%5E2)
So, expression equivalent to is
Option D is correct.

Pos. + Neg. = Pos. if |Pos.| > |Neg.|
Example:
10 + (-9) = 1
|10| = 10 > |-9| = 9
Pos. + Neg. = Neg. if |Pos.| < |Neg.|
Example:
10 + (-11) = -1
|10| = 10 < |-11| = 11
Pos. + Neg. = 0 if |Pos.| = |Neg.|
Example:
10 + (-10) = 0
|10| = 10 = |-10|
Neg. + Pos. the same like Pos. + Neg.
Answer:
Step-by-step explanation:
Answer: x = 7 and y = -2
Step-by-step explanation:
2x +3y = 8 ----------------(1)
x-y = 9 ----------------------(2)
multiply (2) by 2
2x-2y = 18--------------------(3)
subtract (2) from (3)
-5y = 10
Divide bothside by -5
y = -2
Similarly, multiply (2) by 3
3x-3y = 27-----------------------(4)
add (1) and (4) together
5x = 35
Divide bothside by 5
x= 7
Therefore, x =7 and y= -2
Y=x. In parallel lines, the slopes are the same.
