Answer:
The units digit of our number should be and can be any of 0, 2, 4, 6 (four opportunities).
The tens digit of our number should be and can be any of 0, 2, 4, 6 (four opportunities).
The hundreds digit of our number should be and can be any of 0, 2, 4, 6, 8 (five opportunities).
The thousands digit of our number should be and can be any of 2, 4, 6 (three opportunities).
So, there are 4*4*5*3 = 16*15 = 240 such 4-digits totally even numbers, satisfying the condition. ANSWER

Step-by-step explanation:
Answer:
1041
Step-by-step explanation:
Among the numbers 1–1000, there are 31 squares, so the sequence will extend to at least 1031. In those added numbers, there is another square (1024), so the sequence must extend to at least 1032.
There are 7 more numbers that are cubes, but not squares, so the sequence must extend to at least 1039.
And there are 2 additional numbers that are 5th powers that are not squares or cubes. Compensating for the removal of these numbers extends the end of the sequence to 1041.
There are no numbers in this range that are both cubes and 5th powers and that have not already been accounted for. (The only 15th power is 1.)
Hence, the 1000th number in the sequence is 1041.
_____
This result is verified by a computer program that listed the numbers.
11 divided by 20 is .55
then 800 times .55 which equals 440.
800-440 equals
360= answer
