Question

What is the solution to the equation log 2 x – log 2 4 = 2 ?

Answer 1

\[Log_2 x- Log_2 4=2\]

Answer 2

is that right?

Answer 3

yes

Answer 4

\[Log_2 4=a\]
same as asking
\[2^a=4\]

two to what raised equals 4?


I think 2^2=4

so a=2


we may replace
\[Log_2 4\]

with 2

Answer 5

\[Log_2 x-2=2\]

\[Log_2 x=4\]

\[2^4=x\]

x=16
