evaluate the logarithm without using a calculator

OpenStudy (jdoe0001):

kinda hard to do since is blank

OpenStudy (anonymous):

log2(1/32)

OpenStudy (jhannybean):

\[\log_2 \left(\frac{1}{32}\right) = x\]\[2^x = \frac{1}{32}\]

OpenStudy (mathstudent55):

Write 1/32 as a power of 2. Remember to use negative exponents if needed.

OpenStudy (jhannybean):

So first off, as yourself to what power will give you 32?

OpenStudy (jhannybean):

\[2^2 = 4 \ , \ 2^3 8 \ ,\ 2^4 = 16 ...\]

OpenStudy (jhannybean):

Whoop, forgot an equal sign there, meant to write \(2^3 = 8\)*

OpenStudy (anonymous):

2^5

OpenStudy (jhannybean):

Good.

OpenStudy (anonymous):

and would you like to show me an example of ln?

OpenStudy (mathstudent55):

Correct, 2^5 = 32, so 1/32 is 2^ ?

OpenStudy (anonymous):

1?

OpenStudy (jhannybean):

And ...no Remember \(x^{-1} = \frac{1}{x}\)
