Answer:

Step-by-step explanation:

log 25 base 8 = 1.552

First thing you need to do here is to convert the base to the common base which is base 10

To covert to base 10;

Consider the following illustration

log n (in base p) = (log n)/(logp) {in base 10)

The above rule is known as Change of Base

Apply the same rule to the given question:

log 25 base 8 = (log 25)/(log 8)

= (log 5²)/(log2³) = (2log5)/(3log2)

where log 5 = 0.6990 and log 2 = 0.3010

= 2(0.6990)/3(0.3010) = 1.3979/0.9030

⇔㏒25 base 8 = 1.552
