Question

What is 3,482 to two significant figures?

Answer 1

hey mate here is your answer
in significant figure if last 2 digit is 50 or less than 50 thn no change in value
but if last two digit are more than 50 thn replace last 2 digit into 00(and add 100th digit +1)
so here in your case we got
==>3482 last 2 digit are 82 which is greater than 50
So, 3482= 3500 (by adding 100th digit +1)
3482 significant 3500
