Note: An integer has no fractional or decimal part, and thus a perfect square (which is also an integer) has no fractional or decimal part. Calculating n th roots can be done using a similar method, with modifications to deal with n. While computing square roots entirely by hand is tedious. Estimating higher n th roots, even if using a calculator for intermediary steps, is significantly more tedious. For those with an understanding of series, refer here for a more mathematical algorithm for calculating n th roots. For a simpler, but less efficient method, continue to the following steps and example. To calculate n√ a: Ready to take the plunge? Whether you’re looking for a semi-permanent shade that won’t fade after one or two shampoos or prefer something more permanent that lasts four to six weeks – we’ve got you. You’ll find a hair dye to match from top brands such as Revlon, Clairol and Garnier in our range. And when you need to extend the time between hair colours, there’s a handy root touch up that can be sprayed on to help cover any greys or re-growth in seconds, too.

Thumbnails by Felicity.In mathematics, the general root, or the n th root of a number a is another number b that when multiplied by itself n times, equals a.

Taking the square root (principal square root) of that perfect square equals the original positive integer. Some common roots include the square root, where n = 2, and the cubed root, where n = 3. Calculating square roots and n th roots is fairly intensive. It requires estimation and trial and error. There exist more precise and efficient ways to calculate square roots, but below is a method that does not require a significant understanding of more complicated math concepts.

And don’t worry – they’re all easy to apply and hard to get wrong! Read moreDavid Tanis finishes off his celeriac remoulade with chopped chives and a dusting of cayenne pepper. Much as I love crunchy salads, I’m surprised to discover that I prefer the texture of David’s blanched celeriac, which comes closest to my memories of the French kind, being both snappy but slightly yielding. If you’re in a hurry, or like the idea of keeping it completely raw, however, feel free to skip this step. The dressing
