I think surds are like sqaure and cube roots.

What part of the topic have they done? as we spend about 5 lessons on surds at my school.

i think they covered just the mutiplication of surds and using pythagoras theorem to solve them... :dontknow:

Reply 5

the rules for the multiplication of surds are that the square root of a x the sqaure root of b = the sqaure root of ab

eg. square root of 2 x the sqaure root of 3 = the sqaure root of 6

Surds are irrational numbers, they are numbers which cant be written as a fraction. An example of a surd is √2.
There are two rules when mutliplying surds: Here they are:
√ab = √a x √b

and

√a √a
-- = ---
b √b
Where a and b are numbers, i hope that helps a little bit, pm me if you need any more help.

See: http://www.mathsrevision.net/alevel/pages.php?page=40

Did it help you then? I had to cover it in my first lesson, therefore that was good revision for me too! They arent that hard once you have the rules.

Lol, it is not too hard once you get used to it! I used to find it impossible, unti li read the page on it in the C1 text book! If you have the book read it, it is very helpful and gives some examples.

Nutchopper, how do you get the square root symbols in your post?

Reply 13

I typed them in on word and copied and pasted them!!! Its a long way but it is effective :biggrin:

thanks...i havnt got any text books yet....she just gave me a library card and said go and find some. :motz:

Ok well if you do get one read the page on surds, im not sure if you will get the same as me but the one i have got Core mathematics (C1) is really helpful and explains it all with worked examples and questions you can attempt! It even comes complete with examples.

What exam board are you doing? If your doing OCR there are specific books for each module.

I've been given an old book-pure mathmatics 1 and 2, but it's really good even if you have to search for the relevent topics
