I am passionate about travelling and currently live and work in Paris. I like to spend my time reading, gardening, running, learning languages and exploring new places.
Some of the equations are not readable (where a dividing liine is used) plus I found one mistake (ln42 instead of ln2)
So I think you should check the page: algebra/ log/ëxponential-equations-worksheet.

Exercise 1.4: I read that as 4^(x-1)^(1/2) – 2(x-1)^(1/2) – 2 = 0. But your solution does not make sense to me.
So probably you mean 4^(x-1)^(1/2) – 2^(x-1)^(1/2) – 2 = 0. But then your solution still does noet make sense to me. If the answer x = 3 then 16 -4 -2 = 10 (not 0).
Exercise 1.1 2^1 – x^2 = 1/8 is not correct. I haven’t looked at the other exercises yet. Please correct your mistakes.
