the mass of the rock of gibraltar is 1.78 ⋅ 10^12 kilograms. the mass of the antarctic iceberg is 4.55 ⋅ 10^13 kilograms. approximately how many more kilograms is the mass of the antarctic iceberg than the mass of the rock of gibraltar? show your work and write your answer in scientific notation.

Step-by-step explanation:

you have to round it down:

4.55 * 1013

4.55 * 1000

and

1.78*1012

1.78*1000

then take them away

so:

4.55*1000= 4550

1.78*1000= 1780 -

               =  2770

               = 2.77*10^3

The antarctic iceberg's mass is approximately 2.77×10³ times bigger than the mass of the rock of Gibraltar.
