give your answer in standard form.

Calculate, writing the answer in standard form.

1) The parenthesis are useless since multiplication is associative.

1.63 x 10^12 x 2.47 x 10^-1 = 1.63 x 2.47 x 10^11

1.63 x 2.47 = 163 x 247 / 10000 (do the multiplication, also its 10000 since it takes two 100s to move the decimal point out)

You should get 40261 / 10000 and then multiply by 1 followed by 11 zeroes, cancel that out with a 1 followed by 4 zeroes and you get 40261 followed by 7 zeroes, which is **402,610,000,000**.

2) Order doesn't matter for multiplication and division when used together.

8.18/ 5.84 x 10^7 x 10^4 = original

Do long division with 818/584 (you don't have to divide anything extra since 100/100 is 1), you should obtain 1.40068493151. Multiply by 1 followed by 11 zeroes, so move the decimal to the right 11 times = **140068493151**.
