The square root of 196 is 14. Fourteen is a rational number.

196's prime numbers are (2) (2) (7) (7). For example, if you square those prime numbers you would get 14. Why? Because u need equal integers within a square root, so that you can take that integer outside the square root. With the same knowledge, we can apply ask the question whether 196 is a cube root. If it's a cube root, then it needs to have 3 same integer (ex: 3x3x3x4x4x4x; 2x2x2x7x7x7). As you can see we don't have third same integer. Also, even if it is 2x2x2x7x7, it cannot be a cube root because it is missing the third 7. So the answer is that 196 is a perfect square and not a perfect cube. Note: you cannot have a square root of a negative integer, if the question is "is -196 a perfect square or a perfect cube", then the answer is neither. Of course you can SQUARE the negative number (ex: (-2)^2=+/- 4), but you cannot mathematically square root a negative number unless your using the imaginary integer "i". I hope it answers your question and just a bit more.

The "square root" of a number is the number which multiplies by itself to equal the original number:N x N = 196If you multiple 14 by 14, it is equal to 196.On most calculators, there is a square root function:http://www.google.ca/search?hl=en&q=square+root+of+196

The square root of 196 is 14.

The square root of 196 is 14

The square root of 196 is 14.

The square root of 196 is 14

Square root 400 - square root 196 = 6

Yes.

The square root of -196 is: 14 i

sqrt(196) = 14 ====

√196 is rational. √196 = √(14^2) = 14 - a whole number which is also a rational number.

sqrt(-196) = 14i where i is the imaginary square root of -1.

The square root of 196 is 14 because 14 X 14 is equivalent to 196.14

No because 14 is a rational number

√81 + √196 = 23

If you mean the square root of 196/225 then it is 14/15 which is a rational number because it can be expressed as a fraction.

It is the square root of 14*14 = 196.

196 = 14² → √196 is rational.

The square root of 196 is equal to 14.

13, is not the square root of 156, but the best i can give you is that 13 is the square root of 169 and 14 is the square root of 196.

3+14 = 17
