Final Answer:

The value of
log_(d) (7/6) is
0.15415067982725836.

Step-by-step explanation:

To evaluate the logarithm
log_(d) (7/6), we can use the change-of-base formula:


log_(a) (b) =
log_c(b)/log_c(a)

Setting
a = d and
b = (7/6), we can rewrite the given logarithm as:


log_(d) (7/6) =
log_(c) (7/6) /log_c(d)

Since we are given that
log(d) = 1, we can substitute this value into the above equation to get:


log_(d) (7/6) =
log_c(7/6)/1

Now, we need to choose a base c that will make the logarithm on the left-hand side of the equation easier to evaluate. One common choice is to use the base e (the natural logarithm base), which has some nice properties that make it convenient for calculations.

Setting c = e, we get:


log_(d) (7/6) =
log_e(7/6)/1

Using the definition of the natural logarithm, we know that
log_e(7/6) =
ln(7/6) . Therefore, we can rewrite the above equation as:


log_(d) (7/6) =
ln(7/6)/1

Finally, we can evaluate the natural logarithm using a calculator to get:


log_(d) (7/6) =
ln(7/6) =
0.15415067982725836

Therefore, the value of the logarithm
log_(d) (7/6) is
0.15415067982725836.
