How to calculate irrational Surds? (Steps of how to answer it)?

A number is described as rational if it can be written as a fraction (one integer divided by another integer), e.g. 5/7. The decimal form of a rational number is either a terminating or a recurring decimal. A surd is an expression that includes a square root, cube root or other root symbol. Surds are used to write irrational numbers precisely. Because the decimals of irrational numbers do not terminate or recur, they cannot be written exactly in decimal form. To answer your question, you would use surds to better express irrational numbers, such as sqrt(3) and similar numbers, that cannot be expressed with ease. It might be more helpful if you give an example question.

A tutor that understands you

Hi, I'm Rachel! I am currently studying Biology as an undergraduate at University College London and have gained a lot of experience tutoring in the subject over the past couple of years. I love the depth and breadth that Biology offers and I would love to share my passion for the subject with others. I believe in tailoring my education to each individual student, as everyone learns slightly differently so it makes sense to have a lesson that is specifically designed for them. I take time in planning my lessons and work with each student to find the harder topics that need a bit more attention. I am more than happy to answer any questions you have!

Maths tutor with over 150+ hours of experience

I believe learning is about understanding your students and tailoring the lesson to their needs. 1) I first need to understand exactly what areas my students are struggling with and then I design a list of topics to help improve those areas. 2) In my lessons, I always start with a list of starter questions to help get my students thinking, some of those questions relate to the topic and the previous lesson so that would give me a better understanding of how best to approach teaching them the topic. 3) While teaching, I always engage the student and ask them questions to get them thinking. 4) After teaching the topic, we will go through a set of questions. These questions are important as they help me understand how the student thinks about the problem. We will then discuss how they came to their solution enabling me to understand any mistakes they may be making.
