# log2(8x^4/5)

## Enter Logarithm

Expand the following
log2(8x4/5)

## A logarithmic identity states:

 log(a) - log(b)  = log(a) log(b)

With a = 8x4 and b = 5, we have
log2(8x4) - log2(5)

Simplify log2(8x4)
Use the logarithmic identity below
logb(m)n = n * logb(m)
Shift the exponent of 4in front
4log(2(8x)

## One logarithmic identity says:

log(ab) = log(a) + With a = 8 and b = x, we have
4log2(8x) = 4log2(8) + 4log2(x)

4log2(8) + 4log2(x) -log2(5)
