A) \[(292\times {{10}^{6}})km\]
B) \[(2.92\times {{10}^{6}})km\]
C) \[(292\times {{10}^{5}})km\]
D) \[(2.92\times {{10}^{4}})\,m\]
Correct Answer: B
Solution :
Distance between place A and B \[=2.4\times {{10}^{6}}m=2400000\text{ }m\] Distance between place 6 and \[C=5.2\times {{10}^{5}}\text{ }m\] \[=5.2\times 100000\text{ }m=520000\text{ }m\] Distance between place A and C \[=(2.4\times {{10}^{6}}+5.2\times {{10}^{5}})m=(2400000+520000)m\]\[=292\times {{10}^{4}}\,m\] Standard form of \[292\times {{10}^{4}}m=2.92\times {{10}^{6}}\]
