Verified Answer :
The standard form of \(400+5\) is \(\boxed{\bf 405}\).
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:
\(\boxed{\begin{aligned}&\text{H}\ \ \ \ \ \ \ \text{T}\ \ \ \ \ \ \ \text{O}\\ &400\ \ \ \ \ 0\ \ \ \ \ \ \ \ 5\end{aligned}}\)
Here, \(H\) is the hundred's place, \(T\) is the ten's place and \(O\) is the one's place.
The standard form of the number \((400+5)\) is equal to \(405\).
Each place value will be written out separately but all of the place values should be linked together with the plus signs as,
\(\boxed{400+00+5}\)
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:
\(\boxed{400+00+5=405}\)
The above number is the standard form of the expanded number.
Therefore, the standard form of \(400+5\) is \(\boxed{\bf 405}\).
