Simplifying Square Roots of Square Roots by Cyber Tester. Rationalisation is a method of simplifying a faction having a surd either as its denominator or as both the denominator and numerator such that it can be re-written without a surd in its denominator., Simplifying Radical Expressions. z. Radical: square roots and higher roots. z. Shorthand method of writing roots • Use fractional exponent • Not necessarily a fractional value of exponent.

The square root of a number is a value that, when multiplied by itself, gives the number. Example: 4 × 4 = 16, so a square root of 16 is 4. Note that (−4) × (−4) = 16 too, so −4 is also a square root of 16. The symbol is √ which always means the positive square root number inside the square root is closest to and use that to make an estimate. This works well for square roots that This works well for square roots that are relatively close to a perfect square.

If you're asked to estimate the square root of a number that is not a perfect square (without the aid of a calculator) there are some simple steps you can take to find an answer. First, you can estimate to get as close as you can with the aid of two perfect square roots that the number is between. Next, divide the number you're trying to find the square root of by one of the perfect square xn plus 1 would be square root of a times 1 plus epsilon n plus a divided by square root of a 1 plus epsilon n divided by 2. Just plugging it in, the value of xn.
