What's 4v times 10? as in v x v x v x v x 10? i'm so confused.

What you wrote after "as in" is not 4v times 10 .

v · v · v · v · 10  =  v⁴ · 10  =  10v⁴

If "4v times 10" is really what you need,
then you have to think of it like this:

--  4 cows times 10  =  40 cows

--  4 sticks times 10  =  40 sticks

--  4 puppies times 10  =  40 puppies

--  4 'v's times 10  =  40 'v's .    ( 40v )
