Divide these values by one another. The square root basically gives a value which when multiplied by itself gives the original number. 10 We should try to write 243 as a power of 3.
In order to calculate log-1 y on the calculator enter the base b 10 is the default value enter e for e constant enter the logarithm value y and press the or calculate button.
Hence here x sqrt8103 232103 232 103 25 32. An example of the method we should attempt can be shown more easily in evaluating log_2 8. Divide frac10sqrt33 the coefficient of the x term by 2 to get frac5sqrt33. Unfortunately not all logarithms can be calculated that easily.
