2x=1/ square root of x.
None that I feel ought to be included.
The Attempt at a Solution
To answer the question I graphed 2^x and 1/sqrt x individually. They intersect at an x value of 0.5, so x= 0.5.
The problem is that while the answer was correct, the working out was wrong- I did the question differently to how the teacher intended.
I've done some playing around with the problem, moved the variables around and, for lack of better phrase, 'all sorts of stuff'. I'm not really making any headway on it, and this really ought to be a easy question (worth 2 marks in the quiz)
I have a poor knowledge of logarithms.
