Asked by Milan

Find x x^2 * 3x^-2 = 79?

There must be a typo in this question.

Are you sure that's a * not a + Because x²*3x-²=x²*3/x²= 3 Which isn't possible because 3≠79

Hi Milan - Are you certain that you haven't included any typos in your question? The question that you have given has no solution for x. x^2*3x^-2 =79 can also be written as x^2*(3/x^2)=79 in which the x^2*(3/x^2) simply cancels out to be 3, thus we are left with 3=79 which clearly isn't true. So if that is the correct question you have no solutions for x. But maybe double check for any typos just in case! :)

My greatest passion in life is learning and my second greatest passion is teaching which also involves learning. A little bit about me. I was raised in Turkey, France, Pakistan and the UK. I've experienced great success throughout my life due to the amazingly approachable, friendly and unforgettable teachers that I've studied with and from. This, in fact, is the foundation of my commitment to helping my students. I've been tutoring and teaching for 6 years in small and large groups, 1 to 1 lessons to classrooms, from secondary to university students. Feel free to ask me about anything.

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!

Relatively new tutor with 2 months of experience tutoring science and maths.

My name is Zuzanna and I'm currently an A-level student studying biology, chemistry, maths and Spanish. I'm very eager to share my knowledge and hope that you will choose me to be your tutor. In my time at school I have participated in the UKMT maths challenge and received a bronze and a silver certificate on two separate occasions. I have participated in house maths at my school as well as the in the Royal Engineering Masterclass at Brunel University in year 9. These have all helped me gain a deeper understanding of maths and physics. I was also selected to participate in an inter-school Spanish competition in year 8. Recently, I have taken part in Biology Champions and Chemistry Champions from the RVC which have helped me understand the 2 subjects better. I run a STEM club at school for KS2 so have experience in planning lessons and executing them. I have also helped some family members with their work and taught my brother to read in Polish.
