# Last minute c2 questions thread!! watch

1. Hey guys!

With only a day or two today before the C2 exams (across multiple boards), we have decided to make this thread for your last minute revision that you need to secure your wanted grade

If you have any C2 questions, please post them here and someone will be able to help you out!

Feel free to tag me in any questions you post so I can help as soon as possible if I'm around

2. Please try not to post a question without working out unless you are completely stuck.

If you are completely stuck then first try to find a similar example, or in your post throw out your ideas.

could you help me on how they got this:
(x3/2)2 = x3

is it because 1.5 times 2 = 3... :/ omg i'm legit so tired..
Yes it's because 1.5 times 2 = 3

But mainly because the two cancels with the 2 on the denominator of the fraction, since you have to multiply them together.

4. The mark scheme makes no sense to me for Question 13 b)

I thought the 1/2 to the power of x could be 2 to the power of -x. please help

dude,
It says show that, not solve.

How to I get from 2^x + 1 = (1/2)^x to the quadratic?

The mark scheme doesnt show anything to do with a quadratic
