Online, “*” is used to indicate multiplication to avoid confusion with “x” as an unknown.

Unsure of the significance of "V". Is that supposed to indicate a radical?
If what you have is √3x * √121x then
√3x * √121x = √3*121 * √x*x = 11x√3

of course, you garbled the text so much, that may not be what you're after
