Question

difference between significant figure or expontanional notation ?
also three points are required

Answer 1

hey mate here is your short and understandable answer.....

Zeros before the decimal point are placeholders and not significant; in the number .00254, only the 2,5 and 4 are significant, meaning the number has 3 significant figures. ... Exponential digits in scientific notation are not significant; 1.12x106 has three significant digits, 1, 1, and 2.

hope it helps you mark it brainliest if you like ☺
