Answer:
1.18e3 or 1.18e+3
Explanation:
1-Move the decimal 3 times to left so there is one non-zero digit to the left of the decimal point, until the resulting number, m (= 1.18), is greater than or equal to 1 and less than 10
2-Write in scientific notation form m × 10n, where m = 1.18 and n = 3.
Therefore, the number 1180 written in scientific notation is 1.18 × 103 and it has 3 significant figures. Now convert the number to scientific notation. So, we just need to replace the ' × 10n ' by an 'e'.Therefore, the 'e' notation for 1180 is 1.18e+3 or 1.18e3.
