What are the last digits of perfect square?
It is known that the last digit of a perfect square is one of {0, 1, 4, 5, 6, 9}; there are six possibilities. So if we select a digit at random, the probability that it is a possible last digit of a perfect square is 0.6.
Which of the following is a perfect square number?

How many perfect squares are there?
ten perfect squares
They are 4, 9, 16, 25, 36, 49, 64 and 81. However, there are ten perfect squares from 1 to 10. They are 1, 4, 9, 16, 25, 36, 49, 64, 81 and 100.
What are the last digits of perfect squares?
Proving properties about the last digits of perfect squares. We all know that all perfect squares always end in 1, 4, 5, 6, 9, or an even number of zeroes. And we have also noticed that for a number that ends in 1, 4, 9 its tens digit will always be even ( 2, 4, 6, 8, 0 ).
How do you find the tens digit of a perfect square?
We all know that all perfect squares always end in 1, 4, 5, 6, 9, or an even number of zeroes. And we have also noticed that for a number that ends in 1, 4, 9 its tens digit will always be even ( 2, 4, 6, 8, 0 ). If it ends with 6, its tens digit will be odd ( 1, 3, 5, 7, 9 ). If it ends with 5, its tens digit will be 2.
What are the limitations of perfect squares?
– If a number ends with 2, 3, 7 or 8 then it can’t be perfect square. -Square of any natural number has last two digits same as that of last two digits of squares of first twenty–five natural numbers.
How many perfect squares of two numbers are less than 18?
The greatest possible sum of two digits is 9 + 9 = 18. As such, we only need to consider perfect squares less than or equal to 18, of which there are four: 12 = 1 22 = 4
