I have many questions that I need help with.
1. Express 27 (to the power of x) in the form 3 (to the power of ax) where a is an integer to be found.
1(ii). hence solve the equation 3 (to the power of x²) = 27 (to the power of x)
2. √90 in the form a√10 where a is an integer
2(ii). Express (5-2 √3) ² in the form b+c√3 where b and c are integers
3(i). Express 15/2-√2 in the form p+q√2
3(ii). Express √8+√2 / √8-√2 as a single fraction
