value(Expression) -- evaluate

Description

Expressions can be evaluated using value.
i1 : QQ[x];
i2 : f = (x+1)^5

      5     4      3      2
o2 = x  + 5x  + 10x  + 10x  + 5x + 1

o2 : QQ[x]
i3 : e = expression f

      5     4      3      2
o3 = x  + 5x  + 10x  + 10x  + 5x + 1

o3 : Expression of class Sum
i4 : value e

      5     4      3      2
o4 = x  + 5x  + 10x  + 10x  + 5x + 1

o4 : QQ[x]
i5 : value e == f

o5 = true
i6 : c = factor f

            5
o6 = (x + 1)

o6 : Expression of class Product
i7 : value c

      5     4      3      2
o7 = x  + 5x  + 10x  + 10x  + 5x + 1

o7 : QQ[x]
