question 7
simplify:
$\frac{8.85\times10^{-5}}{2.95\times10^{-9}} = \square \times \square$

Explanation:

Step1: Multiply coefficients

$6 \times 2.8 = 16.8$

Step2: Keep the power term

$16.8 \times 10^7$

Step3: (Optional) Standard form

$\frac{16.8}{10} \times 10^{7+1} = 1.68 \times 10^8$

Step4: Divide coefficients

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

Step5: Subtract exponents

$10^{8-5} = 10^3$

Step6: Combine results

$2.3 \times 10^3$

Answer:

1. $16.8 \times 10^7$ (or $1.68 \times 10^8$)
2. $2.3 \times 10^3$
