A^(1/2) = A ^0.5

validation:
A= (√A)^2 = (A^(1/2) )^2 = A^(1/2) * A^(1/2) = A^(1/2+1/2) = A^1 = A

Answer:
(Do the inside first)
1) z-{2z-[3z-(4z-5z)-6z]-7z}-8z
2) z-(2z-(3z- (-1z)-6z)-7z)-8z
3) z-(2z- (-2z) -7z) -8z
4) z-(-3z)-8z
= -4z

I think, double check could be wrong since i rushed it. Hope this helps.

8-5x = 2
+5x on both sides

8-5x+5x = 2+5x
8 = 2+5x
-2 on both sides
8-2 = 2+5x-2
8-2 = 2-2+5x
6 = 5x
divide both sides by 5
6/5 = 5x/5
6/5 = 1x
6/5 = x
x=6/5=1 1/5 = 1.2

[input]8-5x = 2[/input]

So, you know that one side is 90° and one is 8°. A whole triangle equals to 180°. You calculate both sides so: 90 + 8 = 98 and then you subtract it from the triangle so: 180 - 98 = 82°

so the third angle equals to 82°

So wie du schreibst, musst du ehrlich noch in die 1.Klasse gehen. Das ist so armselig Junge! Lern mal deine Rechtschreibung. Ichs ag ja nichts gegen ein paar Fehler, das macht ja jeder Mensch, aber guck dich mal an. Das ist nicht mal normal. Hör auf so einen Mist zu schreiben. Das interessiert niemanden!

5x+3=2
-3 -3
5x = -1

5x/5 = -1/5

x = 0.2

if you don't know if it's right, just put the x in. so ; 5 ( 0.2 ) +3 = 2

i hoped i could've helped you.
