How is 5000000000000000000000000000000000000 constructed?

5000000000000000000000000000000000000 → five undecillion. The coefficient 5 uses a basic vocabulary form rather than a hundreds decomposition.

Which spelling details matter here?

English reads large numbers in three-digit groups. 5,000,000,000,000,000,000,000,000,000,000,000,000 reaches the undecillion group, so the group five is followed by the scale name undecillion. Scale names stay singular inside exact number names. English writes five undecillion without adding a plural s to the scale name. When a three-digit group is 000, English skips that group in the word form. This keeps five undecillion shorter and easier to read.

How should these words be spaced?

American standalone spelling uses spaces between scale groups and hyphens in compound tens.
