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 front4log(2(8x)
One logarithmic identity says:
log(ab) = log(a) +
With a = 8 and b = x, we have
4log2(8x) = 4log2(8) + 4log2(x)
Build our final answer:
4log2(8) + 4log2(x) -log2(5)
