Sure. I will use "sup" now. I didn't know what it was or see it. Thanks for pointing it out. Btw, some answers are wrong from the page I am working on, which I only just proved to be correct. Therefore I have left them out.
Here is the questions.
(2x1/2 3x1/3)2 =
(12a1/2 / 4a1/3)2 = (my answer =36x) a simplify website gave 36x(-10). What is the (-10)?
(2t-1)3 / 6t2 = (i got 2t3)
4t-6 3t3 = fraction? How and why do we solve to a fraction?
I don't understand the reduction at step 7 of *tn. Simply because it is only the sum of the top half of the fraction at 8, and if it were tn on the bottom would it apply the same principle? Am comfortable with the others now.
You are right, just working through the "expected to know stuff in strengthening foundations" and I'm going through maths is fun pages to. We'll have a day to discuss the sheet this week, not sure how many students have it to date. I want to be as up to speed as I can with this. As I do also need to move on to some statistics and trig. Thanks for the thought. And it's mostly self applied pressure atm to get ready and avoid a fast fall.
