Which zero is never significant in a number?
The first zero is known with certainty and the final zero while not known with certainty is still significant. Thus, 4.000 has 4 significant figures. RULE #4 – A zero used to fix a decimal point is never significant.
In which of the following number all zeros are significant?
All zeros between two non-zero digits are significant, no matter where the decimal point is, if at all. Example : In the numbers 0.0000206, 0.0206, 20.6 and 206, the zero lying between the digits 2 and 6 is only significant. ... However, the zeros at the end of such number are significant in a measurement.

What is a leading zero example?
A leading zero is any 0 digit that comes before the first nonzero digit in a number string in positional notation. For example, James Bond’s famous identifier, 007, has two leading zeros. When leading zeros occupy the most significant digits of an integer, they could be left blank or omitted for the same numeric value.
Which of the following numbers has three significant digits?
Answer and Explanation: The correct answer is c. 5.10×10−1 5.10 × 10 − 1 All three digits are significant because the number is expressed in scientific notation.

What is it called when you add a zero without changing the value?
The identity property of 0 , also known as the identity property of addition, tells us that any number + 0 = the original number. Adding zero will not change the “identity” or value of the number you are adding it to.
Why are leading zeros not permitted in Python?
Integer literals starting with 0 are illegal in python, because of ambiguity . An integer literal starting with 0 has the following character which determines what number system it falls into: 0x for hex, 0o for octal, 0b for binary.
