Answer 8

The mass of the Rock of Gibraltar is 1.78 ⋅ 1012 kilograms. The mass of the Antarctic iceberg is 4.55 ⋅ 1013 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.

Answer 9

first multiply both

Answer 10

after you multiply both subtract

Answer 11

1801.36

Answer 12

no multiply both seperately then subtract

Answer 13

Rock of Gibraltar, \(\large\color{slate}{ 1.78\times 10^{12} }\) kg
Antarctic iceberg, \(\large\color{slate}{ 4.55\times 10^{13} }\) kg

Answer 14

4609.15

Answer 15

did you subtract yet?

Answer 16

what I would do is;

\(\large\color{slate}{ ~~~~~~4.55\times 10^{13} }\)
\(\large\color{slate}{ ^{^{\Huge-}}~ 1.78\times 10^{12} }\)
\(\large\color{slate}{ ~~~~^{\text{_______________}} }\)

rewrite:

\(\large\color{slate}{ ~~~~~~45.50~~\times 10^{13} }\)
\(\large\color{slate}{ ^{^{\Huge-}}~~~~ 1.78~\times 10^{12} }\)
\(\large\color{slate}{ ~~~~^{\text{________}} }\)

Answer 17

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

Answer 18

yeah ill let solo take it from here he can help :} bye

Answer 19

\(\large\color{slate}{ ~~~~~~45.50\times 10^{12} }\)
\(\large\color{slate}{ ~~~^{^{\Huge-}}~ 1.78\times 10^{12} }\)
\(\large\color{slate}{ ~~~~^{\text{_________}} }\)

Answer 20

Answer 21

Answer 22

now, subtract them

Answer 23

43.72?

Answer 24

yes, but, \(\large\color{slate}{ ~~~~~~43.72\times 10^{12} }\)

Answer 25

and then re-writing it using a correct scientific notation:

I get: \(\large\color{slate}{ ~~~~~~4.372\times 10^{13} }\)

Answer 26
