The square roots of 4 are -2 and 2.

The square root of 4 is 2

Perfect square roots are the counting numbers {1, 2, 3, ...} The squares of the perfect square roots are the perfect squares, namely 1² = 1, 2² = 4, 3² = 9, etc.

sqrt(4/25) = Â± 2/5

If you have a square root of a number, that means that your "square root" squared (multiplied by itself) will give you your original number. For example: * The square root of 4 is 2. * 2 x 2 is 4.

4 has two square roots. They are +2 and -2.

I think you mean square root. The square root of a number is that number when multiplied by itself will give the original number. For example the original number is 4, then we know that 2 x 2 is 4, hence 2 is the square root of 4. We also know that -2 x -2 is also 4, hence 4 has two square roots, +2 and -2 Similarly 9 has two square roots, +3, and -3 Similarly 16 has two square roots, +4, and -4 Not all numbers have such whole numbers for their square roots. For example the square roots of 2 are nearly equal to +1.4142 and -1.4142. Similarly the square roots of 3 are nearly equal to +1.73205 and -1.73205

The square roots of 4 are -2 and +2. They are rational because they can be written as -2/1 and 2/1.

The square root of 36 x 4 is 6 times 2, which is 12. The roots of 12 are +/-1, +/-2, +/-3, +/-4, +/-6, +/-12.

No. Lots of square roots are not rational. Only the square roots of perfect square numbers are rational. So for example, the square root of 2 is not rational and the square root of 4 is rational.

16*sqrt(3) * 4*sqrt(2) = 16*4*sqrt(3)*sqrt(2) = 64*sqrt(6)

Perfect square roots are the counting numbers {1, 2, 3, ...} The squares of the perfect square roots are the perfect squares, namely 1² = 1, 2² = 4, 3² = 9, etc.
