Rewrite the following in scientific notation and calculate the answer in scientific notation. If necessary, convert your answer to scientific notation.

[tex]\[
\begin{array}{l}
1,960,000 \div 14,000 \\
1,960,000 \div 14,000 =
\end{array}
\][/tex]

(Use scientific notation. Use the multiplication symbol in the math palette as needed. Round to one decimal place as needed.)



Answer :

Sure! Let's solve the problem step-by-step using scientific notation.

1. Rewrite the numbers in scientific notation:

[tex]\[ 1,960,000 \][/tex]

In scientific notation, this becomes:

[tex]\[ 1.96 \times 10^6 \][/tex]

Likewise for:

[tex]\[ 14,000 \][/tex]

In scientific notation, this becomes:

[tex]\[ 1.4 \times 10^4 \][/tex]

2. Set up the division with the numbers in scientific notation:

[tex]\[ \frac{1.96 \times 10^6}{1.4 \times 10^4} \][/tex]

3. Divide the coefficients and subtract the exponents:

- Divide the coefficients:

[tex]\[ \frac{1.96}{1.4} = 1.4 \][/tex]

- Subtract the exponents:

[tex]\[ 10^6 \div 10^4 = 10^{6-4} = 10^2 \][/tex]

4. Combine the results:

[tex]\[ 1.4 \times 10^2 \][/tex]

5. Convert this back to standard scientific notation (if needed):

[tex]\[ 1.4 \times 10^2 = 140 \, \text{(not necessary since it's already simple enough)} \][/tex]

So, the final answer in scientific notation is:

[tex]\[ 1.4 \times 10^2 \][/tex]

In decimal form, this is:

[tex]\[ 140 \][/tex]

And if we multiply it out, we get:

[tex]\[ 14000.0 \][/tex]

Hence, the final answer in scientific notation is:

[tex]\[ 1.4 \times 10^4 \][/tex]
