Find the missing x or b
:
a. log(2)x=2
write the exponent equiv of logs
x = 2^2
x = 4
so we have
log2[4] = 2
:
b. log(b)4=2/3
write the exponent equiv of logs
= 4
Cube both sides
=
= 64
b =
b = 8
so we have
log8[4] =

Solve for x:
Rewrite in exponential form. If , then so...
Solve for b:
Rewrite in exponential form:
Raise both sides to the power.
Simplify.
