When you are using scientific notation why do you use a x instead of a regular multiplication sign?

Purely a matter of convenience. 'x' is an acceptable character that means "multiplied by",
and it appears on the keyboard, whereas the regular multiplication sign doesn't.
Well . . . to be perfectly honest, we don't even know what a "regular multiplication sign" is.

Another contributor agreed:
I was just going to ask that, what is a regular multiplication sign? For 50 years I have been using x
I think he means when he says regular multiplication sign he means the dot that is used for algebra because x is a variable.
P.S. I just learned about scientific notation and asked my teacher the same question. She didn't know.

Why would multiplying numbers in scientific notation be easier than multiplying them the regular way?
Multiplying numbers in scientific notation is easier when the numbers are very, very large or very, very small. Multiplying 0.000000000385 x 0.0000000474 is a pain. Multiplying 3.85 x 10-10 x 4.74 x 10-8 is not.
What does the exponent tell you in a number written in scientific notation?
The exponent in the scientific equation tells you how many decimals to go over because you are multiplying 10 that many number of times. For example, if the number were 1.056 X 107 the number in regular format would be 10,560,000
