y^3=1004
When you see this equation; you should know right the way that the answer of y will be somehow have some never ending decimal place.
The reason is that as you should know 10 x 10 x 10 = 1000
and 11 x 11 x 11 = 1331
so you value of y will be somewhere in between 10 and 11.
and 1004 - 1000 = 4 only a bit more that 1000 which also means a bit more that 10.
The answer of this
y^3 = 1004
y = 1004^(1/3)
y = 10.0133......
y = cube root of 1004
If you want an accurate answer to this, you can use Newton's method. Rewrite it as below:
y^3 - 1004 = 0
all you want is the root of the equation.
divide 1004 by itself 3 times and thats what y equals.
