NEED ANSWER ASAP!!! Express your answer in scientific notation. 9.3 X 107 - 3.14 X 106

kirza4 [7]

Answer:

$89.86\times 10^6$

Step-by-step explanation:

$9.3\times 10^7 - 3.14\times 10^6\\$

In order to simplify the above expressions we make sure that we get same powers of 10 for both the terms.

So, we multiply and divide the first term with 10

Dividing first term by 10.

$\frac{9.3\times 10^7}{10}\\9.3\times 10^{7-1}\\9.3\times 10^6\\$

Now multiplying it by 10.

$10\times9.3\times 10^6\\93\times 10^6$

Evaluating the new expressions.

$93\times 10^6 - 3.14\times 10^6\\$

Taking $10^6$ common factor out.

$(93-3.14)\ties 10^6$

$=89.86\times 10^6$
