Answer:
<h2>10 units</h2>Step-by-step explanation:
It's important to know that the centroid is always two-thirds of the median. Which means
Which means .
But, the centroid has always the same distance from each vertex, which means
Therefore, BG is 10 units long.

Explanation:
Logarithms are used to solve exponential equations. Specifically if you have a variable in the exponent, then you use a log to isolate the variable.
If we set the given log expression to x, then we can rewrite it into 8^x = 1. The only value of x that works is x = 0.
------------
Or put another way,
8^x = 1
8^x = 8^0 ... replace the 1 with 8^0
x = 0 ... the bases are equal (to 8) so the exponents must be equal
------------
You can use the change of base formula to directly calculate this log
