Answer

Answer:

$4.5 \times 10^{2}$ cm

Explanation:

Step1: Set up multiplication

$(9 \times 10^{-3}) \times 50000$

Step2: Rewrite 50000 in scientific notation

$50000 = 5 \times 10^{4}$

Step3: Multiply coefficients and exponents

$(9 \times 5) \times (10^{-3} \times 10^{4})$

Step4: Calculate final value

$45 \times 10^{1} = 4.5 \times 10^{2}$
