Problem 37c

Given information

Given number =  

Step-by-step explanation

Rules to find significant figures for zero:

• Captive zeros (present between the nonzero digits) are significant.
• Leading zeros (present at the beginning of a number) are not significant.
• Trailing zeros (present at the end of a number) are not significant.
• Trailing zeros present after the decimal are significant.

All the non-significant figures are represented by the cross on it.

Since the number has only leading zeroes, which serves to locate decimal. Hence all zero are insignificant as .
