Question

What is the solution to the equation 2 ^1 – 2x = 3 ?

Answer 1

@melissaneedshelp is this your question
\[2^{1-2x}=3\]
?

Answer 2

yes!

Answer 3

@melissaneedshelp Have you studied logarithms?

Answer 4

roughly

Answer 5

Apply \(\log_2\) to both the sides!!!

Answer 6

And tell me what do you get, If you need any help do let me know

Answer 7

\[^{1-2x}= 1??\]

Answer 8

Oh you made a little mistake
We have
\[2^{1-2x}= 3\]
Apply\(\log_2\) to both the sides
\[\log_2 {2^{1-2x}}= \log_2 3\]
Now we know
\[\log_a a^b=b\]
so
\[1-2x=\log_2 3\]
Now we need to look into logarithm tables or use calculator to find \(\log_2 3\)
Can you solve now?
