Question

taking 27as base find the logarithm of 243 upto 4 decimal places. correctly.

Answer 1

Answer:

1.6666

Step-by-step explanation:

Given taking 27 as base find the logarithm of 243 up to 4 decimal places.

We know that log x to base a = b is a ^b = x

So given log 243 to base 27 = 27^x = 243

                                       or 3 ^3 ^x = 3^5 ( 3 x 3 x 3 x 3 x 3 = 243)

                                        3^3x = 3^5

                                    3x = 5 (when bases are same, exponents are equal)

                                    x = 5/3

                                   x = 1.6666
