Answer 2

Answer:

here i think there should be 1

Explanation:

as per rule of multiplication , lowest no of significant figures will determine figures in final answers

2.4*1000000

2.4= 2 significant figures

1000000= 1 significant figures( trailing zeroes not counted )

so product will have 1 significant figure

similiar for (5.5*1000000)

and addition follows lowest significant no in decimal and

2.4 rounded off to 2(1 significant  figure)

5.5 round off  to 6 (same rule )

now 2+6 will be 8

answer 8*10^6

1 significant figure
