Large numbers can be easily written to a required significant figures using the standard notation. So that, the expression on Maria's calculator also can be written in standard form as 2.75 x [tex]10^{4}[/tex]
An exponential function can be used when dealing with large numbers, which can also be written in a standard form. This helps to simplify and express large numbers scientifically.
The value on Maria's calculator = 23,000 + 4.5E3
But,
4.5E3 = 4.5 x 1000
= 4500
So that,
23,000 + 4.5E3 = 23,000 + 4500
= 27500
= 2.75 x [tex]10^{4}[/tex]
Thus,
23,000 + 4.5E3 = 2.75 x [tex]10^{4}[/tex]
Therefore, the expression on Maria's calculator also can be written in standard form as 2.75 x [tex]10^{4}[/tex]
