(1) -2 log_4 (x) = log_4 (9) (2) ln (x + 1) - ln x = 2 1.) A general rule is: Hence: As both sides are to the same logarithm base, we can equate the changing variable hence: Now solve for 2.) A general rule is: Hence: A general rule is: Hence: Now solve for using algebra skills.
Great reply as always. Where have you been, Air?
