Answer:
834.97 rounded to 2 significant figures is 830.
Step-by-step explanation:
To round 834.97 to 2 significant figures, we first need to identify the first two significant digits. In this case, they are "8" and "3". The digit following these two significant digits is "4", which is less than 5, so it will not affect the rounding. Therefore, when rounding to 2 significant figures, we keep the first two significant digits and discard the rest.
So, 834.97 rounded to 2 significant figures is 830.
