What is the quotient of 1.876 ×10^(9) and 6.7 ×10^(6) expressed in scientific notation? Answer:

Divide Decimal Numbers: Divide the significant figures (decimal numbers) of the given numbers. We have 1.876 divided by 6.7. Calculation: 1.876 ÷ 6.7 ≈ 0.280Subtract Exponents: Subtract the exponents of the powers of 10 in scientific notation. We have 10^9 divided by 10^6. Calculation: 10^(9-6) = 10^3Combine Results in Scientific Notation: Combine the results of Step 1 and Step 2 to express the quotient in scientific notation. The quotient is approximately 0.280 × 10^3. However, scientific notation requires the significant figure to be between 1 and 10. So we need to adjust the decimal point.Adjust Significant Figure: Adjust the significant figure to be between 1 and 10 and adjust the exponent accordingly. Move the decimal point one place to the right to get 2.80, which is between 1 and 10. Since we moved the decimal one place to the right, we need to decrease the exponent by 1. Calculation: 0.280 × 10^3 = 2.80 × 10^(3-1) = 2.80 × 10^2

Q. What is the quotient of

1.876 \times 10^{9}

and

6.7 \times 10^{6}

expressed in scientific notation?

\newline

Answer:

Divide Decimal Numbers: Divide the significant figures (decimal numbers) of the given numbers. $\newline$ We have $1.876$ divided by $6.7$ . $\newline$ Calculation: $1.876 \div 6.7 \approx 0.280$
Subtract Exponents: Subtract the exponents of the powers of $10$ in scientific notation. $\newline$ We have $10^9$ divided by $10^6$ . $\newline$ Calculation: $10^{(9-6)} = 10^3$
Combine Results in Scientific Notation: Combine the results of Step $1$ and Step $2$ to express the quotient in scientific notation. $\newline$ The quotient is approximately $0.280 \times 10^3$ . $\newline$ However, scientific notation requires the significant figure to be between $1$ and $10$ . So we need to adjust the decimal point.
Adjust Significant Figure: Adjust the significant figure to be between $1$ and $10$ and adjust the exponent accordingly. $\newline$ Move the decimal point one place to the right to get $2.80$ , which is between $1$ and $10$ . $\newline$ Since we moved the decimal one place to the right, we need to decrease the exponent by $1$ . $\newline$ Calculation: $0.280 \times 10^3 = 2.80 \times 10^{3-1} = 2.80 \times 10^2$
