Sure, let's solve this problem step-by-step.
1. First Number: [tex]\( 814,039 \)[/tex]
2. Second Number: [tex]\( 400,70 \)[/tex]
We need to subtract the second number from the first number.
3. Perform the subtraction:
[tex]\[
814,039 - 40070 = 773,969
\][/tex]
4. We know the expected result is [tex]\( 414,8 \square 9 \)[/tex], and we need to find the missing digit ([tex]\(\square\)[/tex]).
5. Let’s compare the result [tex]\( 773,969 \)[/tex] with the expected format [tex]\( 414,8 \square 9 \)[/tex]:
[tex]\[
773,969
\][/tex]
6. By comparing digit by digit, we can see:
- The first digit (7) does not match any part of [tex]\( 414,8 \square 9 \)[/tex],
- The next digit (7) does not match,
- The third digit (3) does not match,
- The fourth digit (9) does not match,
- The fifth digit (6) corresponds to the blank square,
- The last digit (9) matches the last 9.
Therefore, the missing digit is [tex]\( 6 \)[/tex].
Hence, the missing digit in [tex]\( 414,8 \square 9 \)[/tex] is [tex]\( 6 \)[/tex]. The full result should read [tex]\( 414,869 \)[/tex].
