• A. 1.2053 $\times {10}^7$
• B. 1.2053 $\times {10}^6$
• C. 12.053 $\times {10}^7$
• D. 12.053 $\times {10}^6$

Answer 1

The correct option is A 1.2053 $\times {10}^7$

Given distance is 12053 KM.
We know that,
1 kilometer = 1000 meters
Hence,
12053 kilometers
= 12053 $\times$ 1000 meters
= 12053000 meters
Using scientific notation,
12053000 = 1.2053 $\times {10}^7$

So,
12053 kilometers = 12053000 meters
= 1.2053 $\times {10}^7$ meters
