\\(\frac{6.9 \times 10^7}{2.3 \times 10^{-3}}\\)
\\(\circ\\) a \\(4.6 \times 10^{-10}\\)
\\(\circ\\) b \\(4.6 \times 10^{10}\\)
\\(\circ\\) c \\(3 \times 10^4\\)
\\(\circ\\) d \\(3 \times 10^{10}\\)

Explanation:

Step1: Separate coefficients and powers

$\frac{6.9 \times 10^7}{2.3 \times 10^{-3}} = \frac{6.9}{2.3} \times \frac{10^7}{10^{-3}}$

Step2: Calculate coefficient division

$\frac{6.9}{2.3} = 3$

Step3: Simplify power of 10

$\frac{10^7}{10^{-3}} = 10^{7 - (-3)} = 10^{10}$

Step4: Multiply results

$3 \times 10^{10}$

Answer:

d. $3 \times 10^{10}$
