Question

2^x=1/8
Can someone please explain to me how to solve this?

Answer 1

I did it graphically, and got 2 to a negative exponent I am not ready to post yet.

I think you need to take the log of both sides, but I need to try it to be sure.

Answer 2

^ ^ yes take log both sides that will help to bring down the variable \[ y^x \rightarrow x \ln y\]

Answer 3

@Nnesha Can you explain like i am in 2nd grade? I am so lost and need to learn this for a test tomorrow

Answer 4

log 2^x = log (0.125)

x = log(0.125) / log(2)

Answer 5

OHHHHHHH ok! Now i get it! Thank you @retirEEd

Answer 6

x will equal -3 and I glad I could remember how to do it!
