a rational is a number that can be written as a simple fraction. For example: 9 can be written as 9/1 and .25 can be writen as 1/4.

An irraional number is a number that CANNOT be written as a simple fraction, like pi or e. Also many square roots of non-perfect squares are irrational, like the square root of 3.

You may need to talk this through with a teacher, or go to revision sessions after school if you're not comfortable with some of these maths questions.

You could also look through maths revision books if you are concerned with anything.

Hi, Often the biggest problem is figuring out exactly what the question is asking! If I have understood it correctly you can simplify it to x^4=x^x there are two fairly obvious solutions to this equation one where x=4, then we have 4^4=4^4 which is obviously true. The other solution is x=1. In that case we have 1^4=1^1. since 1 times 1 = 1 and similarly 1 times 1 times 1 times 1 = 1 1^4=1 and so does 1^1. It is very unlikely that there will be any other positive real numbers satisfying this. Note 0^0 is undefined because it essentially boils down to asking what is zero divided by zero and that way leads to trouble so x=0 isn't really a proper solution and anyway 0 isn't really a positive real number as it is neither positive nor negative being exactly the boundary between positive and negative numbers.

i am not good at statistics and probability and number,algebra for foundation

Try:

Past questions and exam papers.

Hope this will help!

pls help me with maaths

anyone know about any website to learn algebra ?

this is super late but bbc bitesize is prety good and covers most basics :)
