Isolate variable 17. Ex: Log3(50)=log50/log3 18.Put parenthesis around 2 terms 19.-20.make denominators the same then solve like a regular equation 21.coefficients turn to powers, only use log once 22.set absolute value = to – and + values 23. A+bi, i2=-1, i3=-I 24.-25. Solve 1st parenthesis 26. Cancel variable (- and +)27.multiply opposite side by the reversed power (3/2 = 2/3) 28. Isolate sq. root, sq. both sides, Set equation equal to (-) and (+) 29. See 19 30. Common denominators 31. Y=(x-h)2 + k, vertex= (h,k) 33.use parenthesis to cross cancel 34. Reverse the x and y 35.
