Texture with smooth gradients from 0 to big numbers

How can I make a texture with 0-1 gradients, like a musgrave texture, become a texture where there are areas with 0 value, areas with big value, like 10000, and still keep smooth gradients?
Should be possible with math I guess, but I can’t figure it out…
(I want to make a volume with smooth changes of density)
Thanks in advance!
