Question

Solve. x=log[2](1/128)

Answer 1

We use logarithm properties/identities to simplify the equation. One of the properties of logarithms is


`log_(a)b = logb/loga`

Applying this property:

x=log[2](1/128)
x = log(1/128) / log 2

Use your calculator to determine each logarithms

x = -2.11 / 0.301
x = -7
