Why don't scientists trust atoms? Because they make up everything!
To answer your question, there are four significant figures in 9.800x10^4. So it's not just significant, it's scientifically significant!
To determine the number of significant figures in 9.800x10^4, we need to count the number of digits excluding any leading zeros. In this case, there are four digits: 9, 8, 0, and 0. Therefore, the number 9.800x10^4 has four significant figures.
To determine the number of significant figures in a number, follow these steps:
1. Identify all the non-zero digits in the number. In this case, the non-zero digits are 9, 8, and the 4 at the end.
2. Count all the digits after the first non-zero digit up to the end of the number. Here, there are two digits after the first non-zero digit, which is 8.
3. The exponent in scientific notation does not affect the significant figures count.
Based on these steps, there are three significant figures in the number 9.800x10^4.
