Respuesta :
The standard form of [tex]400+5[/tex] is [tex]\boxed{\bf 405}[/tex].
Further explanation:
A place value chart is a chart which shows the position of a digit in a number system.
First write the place value at the top according to the given number as follows:
[tex]\boxed{\begin{aligned}&\text{H}\ \ \ \ \ \ \ \text{T}\ \ \ \ \ \ \ \text{O}\\ &400\ \ \ \ \ 0\ \ \ \ \ \ \ \ 5\end{aligned}}[/tex]
Here, [tex]H[/tex] is the hundred's place, [tex]T[/tex] is the ten's place and [tex]O[/tex] is the one's place.
The standard form of the number [tex](400+5)[/tex] is equal to [tex]405[/tex].
Each place value will be written out separately but all of the place values should be linked together with the plus signs as,
[tex]\boxed{400+00+5}[/tex]
Now, add the separate place values together to convert it to standard form.
Remove all the zero place value holders and then combine the remaining digits as shown below:
[tex]\boxed{400+00+5=405}[/tex]
The above number is the standard form of the expanded number.
Therefore, the standard form of [tex]400+5[/tex] is [tex]\boxed{\bf 405}[/tex].
