Determine the number of significant digits in the value 100.10 .

Step-by-step solution

According to the rules for determining significant figures, all non-zero digits are significant. Zeros between non-zero digits are significant, and trailing zeros in a number containing a decimal point are also significant. In the given value 100.10 , the non-zero digits 1 are significant. The zeros between the non-zero digits are significant. The trailing zero after the decimal point is also significant. Therefore, all five digits in 100.10 are significant. The number of significant digits is 5 .
