Question

solve the following.
$(8.43 \times 10^4) \div (2.03 \times 10^2)$
\\(\circ\\) a \\(4.1527 \times 10^8\\)
\\(\circ\\) b \\(4.1527 \times 10^3\\)
\\(\circ\\) c \\(4.1527 \times 10^6\\)
\\(\circ\\) d \\(4.1527 \times 10^2\\)

Explanation:

Step1: Split into coefficient and power parts

$\frac{8.43}{2.03} \times \frac{10^4}{10^2}$

Step2: Calculate coefficient division

$\frac{8.43}{2.03} \approx 4.1527$

Step3: Simplify power of 10

$10^{4-2} = 10^2$

Step4: Combine results

$4.1527 \times 10^2$

Answer:

d. $4.1527 \times 10^2$
