Write √ 128 as a power of 2?

128 = 2x2x2x2x2x2x2 = 2 multiplied by itself SEVEN times, so it is 2 to the power 7. so that leaves you with √2^7 √ = anything to the power 0.5 so that leaves you with (2^7)^0.5 rule of powers involving brackets mean you multiply the power inside the bracket by the power outside the bracket so you get 2^(7x0.5) = 2^3.5 hope this helped!💗

Sherika Logan

ProOnline lessons

Experienced tutor and undergraduate at University of Bristol

Specialising in Maths Tuition. I have graduated with a Maths degree from Bristol in 2012 and since then I have worked in Finance and provided private maths tuition up to GCSE. My approach to tutoring is simple but effective. I would like to have a conversation with the student before our first session in order to understand what their weakness is. I will then work with the students on topics they are struggling with or don't understand with intermediate tests in between to make sure methods are understood. This then helps them persevere at school as they understand concept and exams.

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!

Yahya Abu

Maths | Economics | 6 years experience

Graduated with a First Class Honours in Economics and Finance at Queen Mary University. I have 6 years experience teaching Maths and Economics and love teaching them both from a very basic level to more advanced. I tailor my teaching methods to cater for the needs of different students - and if you’re like me and take time to understand things, dont worry - I will ensure I take things slowly and only move on when you are happy with a topic. I’ve taught over 200 students in total over 6 years and am still looking to help students out with subjects I know.
