Answer: 3.2\times10^6\text{ mm}

=3.2\times10^5\text{ cm}

3.2\times10^3\text{ meters}

Step-by-step explanation:

We know that 1 kilometer = 1000 meters

Therefore, \text{3.2 kilometers =}3.2\times1000=3.2\times10^3\text{ meters}

Also, 1 meter = 100 cm

Therefore, 3.2\times10^3\text{ meters}=3.2\times10^3\times100

=3.2\times10^3\times10^2=3.2\times10^{3+2}\\\\=3.2\times10^5\text{ cm}......\text{[ by product law of exponent]}

Also, 1 cm = 100 mm

Therefore,

3.2\times10^5\text{ cm}=3.2\times10^5\times10\\\\=3.2\times10^{5+1}=3.2\times10^6\text{ mm}......\text{[ by product law of exponent]}
