Solución
Calculate the value by following steps:
- step0: Calculate:
\(9.1\times 10^{6}\times 7.8\times 10^{5}\)
- step1: Multiply the numbers:
\(70.98\times 10^{6}\times 10^{5}\)
- step2: Multiply:
\(70.98\times 10^{11}\)
- step3: Rewrite the number:
\(7.098\times 10^{12}\)
Round the number \( 7.098 \) to nearest thousandth.
Round the number by following steps:
- step0: Round \(7.098\) to \(3\) decimal places using standard rounding method:
\(7.098\)
To simplify the expression \((9.1 \times 10^{6})(7.8 \times 10^{5})\):
1. **Multiply the coefficients**:
\[
9.1 \times 7.8 = 71.058
\]
2. **Add the exponents**:
\[
10^{6} \times 10^{5} = 10^{(6+5)} = 10^{11}
\]
3. **Combine the results**:
\[
71.058 \times 10^{11}
\]
4. **Convert to scientific notation**:
\[
7.1058 \times 10^{12}
\]
5. **Round to the nearest thousandth**:
\[
7.106 \times 10^{12}
\]
Thus, the final answer in scientific notation is:
\[
7.106 \times 10 \wedge 12
\]

The Deep Dive
To simplify the expression \( \left(9.1 \times 10^{6}\right)\left(7.8 \times 10^{5}\right) \), we first multiply the coefficients: \( 9.1 \times 7.8 = 71.058 \). Next, we add the exponents: \( 6 + 5 = 11 \). So we have \( 71.058 \times 10^{11} \). Now, to express this in scientific notation, we need to adjust \( 71.058 \) to \( 7.1058 \) and increase the exponent by 1, making it \( 7.1058 \times 10^{12} \). Rounding to the nearest thousandth, we get \( 7.106 \). Thus, the final answer is \( 7.106 \times 10 \wedge 12 \).
