How do you solve for x in #rx=8=e#?

Answer 1

Is this question correct?

#e# is normally used as a reserved constant and is of value
#2.71818....# It is one of the 'Irrational numbers'
So as the constant #e=2.71818..# it is not correct to write #8=e#
#e# is so important that it is even used as a logarithmic base normally written as 'ln'

So in the same way you could have log(10) you can have ln(10)

'~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ #color(red)("Assumption: The question is wrong")#
Suppose the question should read as:#color(brown)(" " rx=8)#
Then divide both sides by # color(blue)( r)# giving:
#" "color(brown)(r/(color(blue)(r))xx x=8/(color(blue)(r)))#
But #r/r=1# giving:
#" "x=8/r#

Answer 2

To solve for (x), you would first divide both sides of the equation by (r) to isolate (x), giving you (x = \frac{8}{r}).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
