Which of the following numbers will produce the same number when rounded to two significant figures? (2.3)

prohojiy [21]

2.10

The 0 after 1 is not significant and does not affect the value of the number; therefore, when the number will be rounded to two significant figures, it will become 2.1, so it will be the same.
