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

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

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