Answer 1

\(\Large\color{blue}{ \rm ~1 \times (-3)=-3}\)

\(\Large\color{blue}{ \rm ~(-3) \times (-3)=9}\)

\(\Large\color{blue}{ \rm ~9 \times (-3)=-27}\)

\(\Large\color{blue}{ \rm ~(-27) \times (-3)=81}\)

\(\Large\color{blue}{ \rm ~81 \times (-3)=-243}\)

\(\Large\color{blue}{ \rm ~(-243) \times (-3)=729}\)
