I find algebra fun. But, I haven't had a lesson with my teacher today. So, I haven't been anything new. I am actually taking maths privately.
Basically, I will need it to study Physics at University. I am in 2nd year A levels for my other subjects. The aim is to get through Maths AS and A2 so I can take them the same time as my other A levels. InshAllah.

So, do you or anyone else know of any good websites to get me to keep my brain going during the holidays?

Erm...What Exam board are you doing...because if its Edexcel...I can give you a site with Past Papers and model solutions.

My private tutor has not told me what borad-yet. I believe she would have today, but something came up.
Could you kindly send the Edexcel link?

JazakAllah akhee.

Given that 256=4 (to the) k
Write down the value of k

I did:

k = 256
----
4

k = 64

But, the answer is wrong. It is meant to be: 4.


Can someone help please?

wasalam

^yeh those are both right

256 = 4^k
log256 = k log4
log256/log4 = k
k = 4

I think gives correct answer... check on a calculator...

Salam,
Yes, alhamdullilah it has given the right answer.
I didn't know you had to use log in this.

I'd first take log of both sides to make

Log 256 = Log 4 (to the K)

The K can be moved (due to Log laws) before the log to make:

Log 256 = K Log 4

Move the Log 4 to the other side to get:

Log 256/Log 4 = K ( / = divided by)

This should give you the answer 4

Just remember its not 256/4....its LOG 256/LOG 4 (this is a common mistake)

I can understand why people don't like A level mathematics.
Hmm..I doubt I'll be giving up though.

JazakAllah for your help-everyone!
