Can someone solve this for me with their explanation please?
Lana71 [14]

First you want to subtract 36

so it looks like this \sqrt[4] {(4x+164)^3}=64

Then you want to cancel out the square root 4 by raising that to the 4th power (you must do this to both sides)

{(4x+164)^3}=64^4 which is equal to {(4x+164)^3}=16777216

Then you take the cube root to both sides [tex]\sqrt[3]{(4x+164)^3}=\sqrt[3]{16777216}[tex]

Then you end up with the equation 4x+164=256

Then subtract 164 to both sides

4x=92

then divide 92 by 4

Then you get x=23

If M is the midpoint of LN = 27.8 , find the length of MN
Mars2501 [29]
Midpoint is almost like half. 

So, I am assuming that LN is one line and M represents the point that can divide L and N evenly.

27.8 / 2

13.9 = half of the line. 

Since MN would be the center to the end of one line, it would equal 13.9.

Have a nice day!
