Yes, Any real number squared is a real number. In this case that number is 25.
If x squared = 5 then x = sqrt(5) = 2.2361 (approx).
Yes, Any real number squared is a real number. In this case that number is 25.
Yes, it is a real number.
5 squared is 5*5 is 25. 25 is not an irrational number.
The square root of 5 squared is 5, which is a rational number.
Yes, when you multipy a number by itself it is called squaring the number. 5 squared = 5 times 5 = 25
5*n2
It is: 5*5 = 25
It is not the square of a whole number; but it is the square of a real number. If you calculate the square root of 23, you will get a real number. That real number times itself will equal 23. But the square root will not be a simple whole number. It will have an endless decimal fraction.
Yes, it's 400.
Use the Pythagorean theorem. 5, -5, 5i, and -5i will work, as well as any combination of a real and imaginary number such that (real part) squared + (imaginary part) squared = 25, for example, 4 + 3i, 3 + 4i, 4 - 3i, etc.
There are infinitely many such numbers. One such is 181.81828384881882883884...
