How many significant digits are in 89015
Lilit [14]

Answer:

Total 5 significant digits.

For example, digit 013 has the 2  significant digits and zero is not a significant digit because digits 1 and 3 give meaningful contribution but digit zero does not value meaningful contribution. Similarly, the 89015 has a total of 5 significant digits and these digits are the 8, 9, 0, 1,  and 5.
