I am doing my P2 retake in Novemeber... after getting an unimpressive 69% in June last year... Once again I have stumbled upon my arch nemesis, logarithms! Those nonsensical and pointless fellows of the exponential function and demons catering to such a devils whim... Now I am more angry than ever with them... and am going to defeat them in battle.
PLEASE can someone show me the full method for how to answer these questions from Heinemann P2. Pg 113:
16. 3^(2x + 1) = 3^x + 24
18. 4^2x + 48 = 4^(x + 2)
21. Find the values of x for which
log3x - 2 logx3 = 1
22. Solve the equation:
log3(2 - 3x) = log9(6x^2 - 19x + 2)
