Which of the following is equivalent to log840 rounded to three decimal places? 0.599 0.898 1.564 1.774

log8 (40) = log 10 (40)/ log 10 (8)

               =1.773976

to the nearest thousandth

   = 1.774

0.5637

Step-by-step explanation:

We'll use the change of base formula:

log to the base a of x = [log to the base 10 of x] / [log to the base 10 of a].

In this case, the base is a = 8 and x is 40.

Thus, log to the base 8 of 40 =

               log to the base 10 of 40

                  log to the base 10 of 8

and this comes out to:

                                               log 40      1.60206

log to the base 8 of 40 = = = 0.5637

                                                 log 8       0.90309

the infinity sign

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
