You can tell by the nature of this question that it is expecting you to see a pattern in the tens column wen raising powers of five, and not to actually calculate the value of 574.
So let's take a look:
52 = 25
53 = 125
54 = 625
56 = 3125
...
As you can see, the last two digits are always "25", so the answer to your question is 2.
The reason the last two digits are always 25 is because of the effect multiplication has on the number. Consider: 5 * 25 = 125. No matter what happens to any digits to the left of those, the last two will always be 25 as a result.
It is 2.

Oh, isn't that a happy little math problem! If we have a number where the ones digit is 5 more than the tens digit, we can create a beautiful equation like this: Let's say the tens digit is "x", then the ones digit would be "x + 5". So, the number would be 10x + (x + 5). Happy solving, my friend!

3 more than 5 is 8, so the tens digit is 8. The tens digit is,double the number of the ones digit, so divide 8 by 2 and you get 4. If you double 4 it is 8 so, the number is 84.
The answer depends on what the tens digit is greater than, and what the ones digit does then.

To round 5555 to the nearest hundred, look at the tens digit (5 in this case). If the tens digit is 5 or greater, round up to the next hundred. If the tens digit is 4 or less, round down to the previous hundred. In this case, the tens digit is 5, so you would round up to 5600.
Look at the tens digit. If it is 5 or more, round up. If it is 4 or less, round down. Examples: 83 - tens digit is more than five, round up to 100 447 - tens digit is 4 or less, round down to 400 1053 - tens digit is 5 or more, round up to 1100 650 - tens digit is 5 or more, round up to 700 649.999 - tens digit is 4 or less, round down to 600

This is missing some information. You mentioned the tens digit twice and didn't mention the ten thousands digit. One possibility is 87184.
