Hi all, I recently went through this A maths question with one of my students who asked me this question. See if you can solve it. Answer will be announced few days later.
To solve this question, we can use a double substitution, meaning we substitute both y = lg x and 10^y = x into the same question. See the following worked solution. The idea here is to think creatively and unconventionally when solving maths questions. Anything is possible to solve a question as long as one does not violate any mathematical rules. Let your creative juice runs! Have fun!
