5 is a rational number and it is also a prime number
Yes -10 is a rational number
Not necessarily. If it is the same radical number, then the signs cancel out. Radical 5 times radical 5 equals 5. But if they are different, then you multiply the numbers and leave them under the radical sign. Example: radical 5 * radical 6 = radical 30
A radical number is a number with a decimal. so a radical expression would be like 5 raised to the 2.5 power.
If the product of two irrationals is a rational, then they are both the same radical of a non-perfect square. For example, radical 5 times radical 5 is 5, since that is by definiton what a radical is.

The square root (radical) of 5 is about 2.2361 (an irrational number)
A radical number is a number with a decimal. so a radical expression would be like 5 raised to the 2.5 power.
Here is an example, radical 20 plus radical 5. Now radical 20 is 2(radical 5) so we can add radical 5 and 2 radical 5 and we have 3 radical 5.
If the product of two irrationals is a rational, then they are both the same radical of a non-perfect square. For example, radical 5 times radical 5 is 5, since that is by definiton what a radical is.
Sqrt(25) is -5 or +5, both of which are rational.
2 times radical 5 or about 4.472135955
5/9 OR 0.5 repeating.. here's how: "radical 5 over 3" times "radical 5 over 3" (because squaring means to multiply a number by itself) is "radical 25 over 9". this is not complete: the square root of "25" is "5" so the final answer is 5/9. "5" divided by "9" is "0.5 repeating".
Sqrt[5*radical(68)] = -6.4211 and +6.4211.
