I should have read more closely, two significant figures would be
\(5.1 \times 10^6\)

i got that, how can u write it in significant figures?

Answer 16

\(5.119 \times 10^6\) is four significant figures

\(5.12 \times 10^6\) is three significant figures

\(5.1 \times 10^6\) is two significant figures

\(5 \times 10^6\) is one significant figures
