77 is not a perfect square.
Another way to look at it is this (use a calculator)
sqrt(77) ~= 8.774964387
Notice how there is no point where the numbers begin to repeat themselves (e.g., 1.222322232223)
Both reasons tell us that sqrt(77) is an irrational number.

Yes - the square roots of all non-perfect square integers (ie the numbers which are 1², 2², 3², ...) are irrational.
Irrational
The square root of 5929 is 77. This is because the square root of a number is a value that, when multiplied by itself, gives the original number. In this case, 77 multiplied by 77 equals 5929. Therefore, the square root of 5929 is 77.
8.78
It can be written as a fraction, so it is rational.
Geometric Mean of two numbers is the square root of their product, in this case root 77 ie 8.775
Irrational
The square root of 5929 is 77. This is because the square root of a number is a value that, when multiplied by itself, gives the original number. In this case, 77 multiplied by 77 equals 5929. Therefore, the square root of 5929 is 77.
77 is not the square of an integer. Rounded to five decimal places, its square root is equal to 8.7750.
It's not the square root of 77.
The square root of 77, written √77 is ± 8.775 (3 dp)roughly 8.775
Square root of 693 = 3 square root of 77 or 26.325
A rational number is one that can be expressed as a ratio or a fraction: 1:5, 2/7, 23/77. An irrational number cannot. If you can write it as a decimal which ends or repeats, it is rational. Typical irrational numbers are things like pi (3.1415926535...), e (2.71828...), and most square roots (root 2 = 1.4142...).
No, 77 is not a square number.
8.78
between 76 and 77 76² = 5,776 77² = 5,929 76.36753236814713
sqrt(77)/9 cannot be simplified.
The square root of 49 is 77, because, 7 x 7 = 49.
