the 2nd pic is why does 2=log3=2*loga +log3
the times confusing me
i know where the log(base a)a comes from because it equals 1
0
#4
the third pic is the circle question is confusing
my working out
x=log3^(0.5)
so
3^(0.5)=log2^(x)
then takes log both sides
you finally get
log3.5/log2=x
x=1.807

Judging by the 'your' in the title and the bog standard c1/2 questions, you'RE not very clever.

You do realise that this is a help forum....if you're stuck and post a question people will respond, but if you entitle it "help if your clever...test your self" it'll put people off answering. Also the pictures are out of focus; it's hard to make out the questions.

Make your title descriptive, not unique. Unique is fine if you have clickbait, but you're looking for help, not ad revenue.

Press edit of the first post. And then advanced edit and you'll be able to change the title.

You have , so if you've got

then . Then rearrange and solve the quadratic.
