Answer 1

\[\left( 8\times10^{7} \right)\left( 7\times10^{4} \right)\]

Answer 2

\[8\times 7\times 10^7\times 10^4\] is a start
then add up the exponents, and also multiply \(8\times 7\) there is one more step after that

Answer 3

\[56\times10^{11}\]

Answer 4

yeah good
but still one more step

Answer 5

divid by 10 ?

Answer 6

it is not in scientific notation, because \(56>10\) so turn it in to \(5.6\) then kick the exponent up by 1

Answer 7

you should get as a final answer \[5.6\times 10^{12}\]
