Rational; 62 = 36. Any rational number that is squared is still rational.
It will be radical(62). It cannot be simplified.

The square root of 72 is 6x(sqrt2). You can find this by breaking 72 down into its prime factors (2x6x6 or 2x62). You can then take the square root of each part which means the 62 will become 6 and then because the sqrt2 is an irrational number it is left under the sqrt sign.

Rational; 62 = 36. Any rational number that is squared is still rational.
It is a rational number because it can be expressed as a fraction in the form of 62/1
Some are and some aren't. 62 is real and rational. 1/3 is real and rational. sqrt(2) is real and irrational. (pi) is real and irrational.
Because there are no integers x and y tat are coprime, such that x/y = sqrt(62). The proof requires knowledge of the unique prime factorisation theorem. If you know that theorem, you will have also learned why sqrt(62) is irrational. And if you have not, this site is not best suited to learn about the theorem.
Such that, rounded to two decimal places, the square root of 62 is equal to 7.87, the square root of -62 is equal to 7.87 i. ============================================================= You cannot have a square root for a negative number as the multiplication of any number with itself will ALWAYS give a positive number
31 is rational. All integers are rational since they can be expressed as a fraction of integers. 31 = 31/1 = 62/2 = 93/3, etc.

a2 + 62 = 122 a2 + 62 - 62 = 122 - 62 a2 = 144 - 36 a2 = 108 taking the square root of each side, we get a equal plus or minus the square root of 108, or plus or minus 6 times the square root of 3.
