Make a four digit below

Explain why the number is even - 5,6,7,3, _, _, _, _
How would you get this?

6573

A number is even if it't one's digit is divisible by two. Of the four numbers 5,6,7 and 3, only 6 is even, so the number must end in 6. The other digits can be in any order.
I'm not sure if this is what your question was asking or not. If not, repost the question.

The volume of a swimming pool is (36x^5-12x^3+6x^2) cubic ft. if the height is 2x ft. and thw width is 3x ft., find its length.

i am four-number.my ones is 1.my thousands digit is five times my ones digit.my tens and hundreds digits are the same.the sum of my digits is 10.what number am i?

To find a four-digit number below 6573, an approach would be to choose the digits for the thousands, hundreds, and tens place and then determine the digit for the ones place.

Given that the question asks for an even number, we know that the ones place digit must be even. The options given are 5, 6, 7, and 3. From these options, only 6 is an even number. Therefore, the ones place digit can be 6.

For the remaining three digits, there is no specific criteria mentioned, so they can be chosen in any order as long as they are different from each other.

Here is an example: 6573

Therefore, a valid four-digit number below 6573 that satisfies the condition of having an even ones place digit is 6573.
