Answer 5

Rock of Gibraltar, 1.78×1012 kg
Antarctic iceberg, 4.55×1013 kg

Answer 6

4609.15

Answer 7

what I would do is;

4.55×1013
− 1.78×1012
_______________

rewrite:

45.50 ×1013
− 1.78 ×1012

Answer 8

is this a good answer?

Step 1:
4.55 x 10^13
- 1.78 x 10^12
------------------
rewrite -

45.50 x 10^12
- 1.78 x 10^12
-------------------
43.72 x 10^12

Step 2:
Then re-write it using correct scientific notation.
4.372 x 10^13.

Answer 9

oh I mean that when I re-write the 45.50 is times 10^12, not 10^13.

Answer 10

45.50×1012
− 1.78×1012
_________

Answer 11

and btw @supersmart1001 you got that from google lol i saw that too

Answer 12

and then re-writing it using a correct scientific notation:
I get: 4.372×1013 XD

Answer 13

but can you explain to me how
43.72 x 10^12 because to the power of 10^13?

Answer 14

?

Answer 15

like when you rewrite using correct scientific notation it becomes 4.372 x 10^13.
but before it was 10^12.. now why does it change to the 10^13?

Answer 16
