## anonymous one year ago what is the simplified for of the expression in the comments. answer in scientific notation need to show work

1. anonymous

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

2. anonymous

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

3. anonymous

$56\times10^{11}$

4. anonymous

yeah good but still one more step

5. anonymous

divid by 10 ?

6. anonymous

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

7. anonymous

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