Sagot :
Answer:
4 significant digits
Explanation:
To determine the number of significant digits in the number 1982000, we need to consider the rules for identifying significant figures:
All non-zero digits are significant.
Zeros between non-zero digits are significant.
Leading zeros are not significant.
Trailing zeros in a number without a decimal point are not necessarily significant unless specified by a bar, underline, or context (like scientific notation).
Given the number 1982000:
The digits 1, 9, 8, and 2 are all non-zero and thus significant.
The trailing zeros (000) are ambiguous without additional context (e.g., a decimal point or scientific notation). If no further context is provided, we assume they are not significant.
Thus, in the number 1982000, there are 4 significant digits: 1, 9, 8, and 2.
