Answer:
Option 3 - [tex]2.04\times 10^4[/tex]
Step-by-step explanation:
Given : Numbers [tex]7.2\times 10^{-6}[/tex] , [tex]3.09\times 10^3[/tex][tex]2.04\times 10^4[/tex] and [tex]5\times 10^3[/tex]
To find : Which number is largest ?
Solution :
We solve all number in standard form,
1) [tex]7.2\times 10^{-6}=\frac{72}{10}\times \frac{1}{1000000}[/tex]
[tex]7.2\times 10^{-6}=0.0000072[/tex]
2) [tex]3.09\times 10^3=\frac{309}{100}\times 1000[/tex]
[tex]3.09\times 10^3=3090[/tex]
3) [tex]2.04\times 10^4=\frac{204}{100}\times 10000[/tex]
[tex]2.04\times 10^4=20400[/tex]
4) [tex]5\times 10^3=5\times 1000[/tex]
[tex]5\times 10^3=5000[/tex]
The decimal number is the least number among all.
The five digit number is the greatest number among all.
So, 20400 is the greatest number.
Which means [tex]2.04\times 10^4[/tex] is the largest number.
Therefore, Option 3 is correct.
