70.700, 70.07, 7.070, 7.007.
1.050 -> 1.1
8.964 -> 8.96

You subtract exponents when dividing exponents
0.5 is the first way
1/2 is the second way
50% is the third way.
Hope that helps bud :).

-4c - 11 = 4c +21 add 4c to both sides
</span>
<span>
-4c - 11 + 4c = 4c + 21 + 4c simplify
- 11 = 8c + 21</span> <span> subtract 21 from both sides
- 11 - 21 = 8c + 21 - 21 </span><span>simplify
- 32 = 8c divide both sides by 8
c = - 4That's it

I hope you got
the idea
