㏑(8^2) = ㏑(64)
or
㏑(a^n) = n㏑(a)
so
2㏑(8) = ㏑(64)
Is it what you mean by logarithmic equation ?
You drive 60 miles in 1 hour.
The formula in finding the formula of a decagon is to simply
just add the measurement of all the sides of decagon. A decagon is a shape
having 10 equal sides. To get the length of each side you have to divide 10
from the perimeter.
350 feet / 10 sides = 35 feet each side
Therefore, the length of each side is 35 feet.
