After solve(...) I get

x = (2/9*sqrt(3)*sqrt(1355) - 611/27)^(1/3) + 61/9/(2/9*sqrt(3)*sqrt(1355) - 611/27)^(1/3) - 8/3

Now how to show this as decimal? float(x) and R = RealField(50); R(x) doesn't seem to work.

After solve(...) I get

`x = `

~~(2/9~~(2/9*sqrt(3)*sqrt(1355) - 611/27)^(1/3) + *sqrt(3)*sqrt(1355) ~~61/9/(2/9~~61/9/(2/9*sqrt(3)*sqrt(1355) - 611/27)^(1/3) - 8/3*sqrt(3)*sqrt(1355)

Now how to show this as decimal? float(x) and R = RealField(50); R(x) doesn't seem to work.

After ~~solve(...) ~~`solve( x^3+8*x^2+x+10 , x )`

I get

`x = (2/9*sqrt(3)*sqrt(1355) - 611/27)^(1/3) + 61/9/(2/9*sqrt(3)*sqrt(1355) - 611/27)^(1/3) - 8/3`

Now how to show this as decimal? float(x) and R = RealField(50); R(x) doesn't seem to work.
