9. 92 = 81. The difference of the digits 8 and 1 is 7.

Two digit no and the sum of the two digit give 12 39,48,57,66,75,84,93 are the possible two digit no whose sum is 12. Example 3+9=12;4+8=12...... Difference of the two digit no is 2 that is 57and75. because difference of 5 and 7 is 2. Next, unit digit to be greater than tens digit. So 57 is ans because 7 is in unit digit which is greater than tens digit.

4*4=16,1+6=7 5*5=25,2+5=7 6*6=36,3+6=9 7*7=49,4+9=13 8*8=64,6+4=10 9*9=81,8+1=9 so 9 square is 81 sum of these two digit is 9. 9 square is answer.
what is the difference between the largest 8-digit number and the smallest 6-digit number
The largest 3-digit number - not itself a perfect square - is 999. Calculate its square root, round the answer down, then square the answer again.
The difference is 90000000

3,162.27766 is the square root of a smallest 8 digit number and thus the greatest integer having the greatest 7 digit square is 3,162. This is because the square of the next integer i. e. 3,163 is going to be an 8 digit number as discussed above. Thus, 3,162 is the required answer. 3162^2 = 9998244.
9998244 (3162 sqrd)
If one digit is a prime number, that digit must be 2, 3, 5, or 7. If one digit is a square, that digit must be 1, 4, or 9. If one digit is neither a prime number or a square, that digit must be 0, 6, or 8. So, 248 is a possible number. Another possibility is 436. There are other possibilities, as well.
It is the same as the difference between a blue square and a square.
Single digit primes are 2, 3, 5, 7 Single digit squares are 1, 4, 9 Neither prime nor square are 0, 6, 8 None of that makes a difference if we can't figure out what a "grerate" is. I'll guess you want to know the greatest possible number given those conditions. That would be 985.
7 is.
As 1 million is the lowest 7-digit number and also the square of one thousand, the number you seek is the square of 999, which I'm sure you can calculate!
Because the number is the square of its units digit, it must be the square of a number between 1 and 9. Look at the squares of the first nine numbers.The square of 1 is 1.The square of 2 is 4.The square of 3 is 9.The square of 4 is 16.The square of 5 is 25.The square of 6 is 36.The square of 7 is 49.The square of 8 is 64.The square of 9 is 81.Of these numbers, 1, 25, and 36 are squares of their units digit.
