4.8x10¹x2.0x10²= ?


Would 4300 be written as 4.3 x 10³ or as 4.300 x 10³? Is it the first because there is no decimal after the zero. If it were 4300. it would be the second answer. Am I correct?

Thanks so much for any *delete me*

well actually you can write in both ways but it depends how many significant factors do you want..!
