1.548937075 x 10 to the 12th. round the number to 3 significat figures.
I thought I would respost this because the other one was getting confusing
Three significant digits? That means the hundredths digit is to be rounded. Does the 8 in the next digit make the 4 go to 5?
Yah, so would you not even look at the 10 to the 12th part of it?
Yes, that stays, but it has nothing to do with the rounding.
ANS: 1.55 x10^12
Thanks so much.

To round a number to three significant figures, you need to identify the first three most significant digits and adjust the remaining digits accordingly.
In this case, the given number is 1.548937075 x 10^12, which can be written as 1,548,937,075,000 (expanded form).
To round this number to three significant figures, we start from the left:
1,5 4 8,937,075,000
The digit in the fourth place (8) is the first digit that is not significant. Since it is greater than or equal to 5, we will round up the last significant digit, which is 4.
Therefore, the rounded number to three significant figures is 1.55 x 10^12.
