Thread: How exatcly do you work out Surds?

Just wondered how exatcly do you work out Surd values without using a calculator?

how does the calculator work it out? what is the rule of a surd?

thanks.

The "standard" way to calculate surds with out a calculator is to use taylor expansions to approximate the actual solution. Calculators do a similar thing, expect they use series that converge quicker.
