Question 71566: PLEASEEE HELP ME SOLVE FOR X WHEN
2=(x/100-x)^3

You can put this solution on YOUR website!
2 = (x/100-x)^3
:
Do you mean:
%28%28x%2F100%29-x%29%5E3 = 2
:
or do you mean:
%28x%2F%28100-x%29%29%5E3 = 2
:
Assume it is the 2nd one: find the cube root of both sides; (Cube root = ^1/3):
:
x%2F%28100-x%29+=+2%5E%281%2F3%29
:
x+=+2%5E%281%2F3%29%28100-x%29%29; multiplied both sides by(100-x):
:
x+=+%28100%2A2%5E%281%2F3%29%29+-+%28x%2A2%5E%281%2F3%29%29
:
x+%2B+x%2A2%5E%281%2F3%29+=+100%2A+2%5E%281%2F3%29
:
x%281+%2B+2%5E%281%2F3%29%29+=+100%2A+2%5E%281%2F3%29: factor out x
:
x+=+%28100%2A2%5E%281%2F3%29%29%2F%281%2B2%5E%281%2F3%29%29: divide both sides by 1%2B2%5E%281%2F3%29
