Evaluate log(-13)<br> Correct answer will get brainliest
Sedaia [141]

if given log(a)=b, where no base is stated, we assume base 10, or log(a)=log_{10}(a)

also, log_a(b)=c translates to/can be written equivilently as a^c=b


therefore, given

log(-13)=? where we want to find ?

assume base 10 and translate

10^?=-13

since we cannot raise a positive number to any real power and give a negative number, ? is not a real number and therefore, there are no real solutions


if we do want to find a solution, we can use Euler's idendity

e^{\pi i}=-1 where i is the complex number i=√-1 and e is euler's number

we can try to change bases to find the value of ?

e^{\pi i}=-1

13e^{\pi i}=-13

so

13e^{\pi i}=10^?

taking ln of both sides

ln(13e^{\pi i})=ln(10^?)

using log rules

ln(13)+(\pi i)ln(e)=(?)ln(10)

ln(13)+\pi i=?ln(10)

divie both side by ln(10)

\frac{ln(13)+\pi i}{ln(10)}=?

in a+bi form

?=\frac{ln(13)}{ln(10)}+\frac{\pi}{ln(10)}i



there are no real numbers that it evaluates to

however, it does evaluate to a complex number which is \frac{ln(13)}{ln(10)}+\frac{\pi}{ln(10)}i or aproximately 1.11394+1.36438i

Which number is rational -3 1/2, sqrt 5, pi, 9.23157...
PIT_PIT [208]

-3 1/2 is rational because the decimal ends at -3.5. It is not sqrt(5) because the decimal never ends and the same follows for pi and 9.23157.
