Exponentials and logarithms would be the most relevant chapter (section 14.6 should help if you're using the Edexcel year 1 textbook)

You sure.

I thought it’s about manipulating powers.

If it logarithms then never mind this question.

It's Exponentials. Or indices, if you call them that. Manipulating powers is just a sub-topic under this topic.

In most maths textbooks, you'll find it under the chapter called 'Exponentials and Logarithms'. You should check a person's suggestion before being dismissive especially when you 'got no idea' what topic it is

This is Exponentials and Logarithms because you have to take Log to both sides to find x. This is only taught in that chapter. I know this cause this is the Edexcel Textbook which I am doing

You don't need to take logarithms in this case - if you write both sides as a power of 3 then you can use the fact that 3^a = 3^b => a = b to write down an equation involving x

Google " indices equations" for videos and extra questions/examples.

I tend to teach this to year 9+ students (and sometimes some bright year 8 pupils)as it's one of those topics which gets overlooked in school, but which pops up now and again on GCSE papers. The fact you don't recognise it kinda proves my point LOL.
