Question

Round to 4 significant figures
4,567,985

Answer 1

4,568,000 without scientific notation, as the absence of a decimal reads from right to left, and zeros don’t count before the first non-zero digit.

Example:

1,100 has two significant figures

OR

4.568 x 10^6 with scientific notation. The decimal indicates reading left to right, excluding zeroes before the first digit from the left.
