You're dividing by 6 on both sides of the original equation

#

The original equation is $$\frac{9}{11}=6e^{\frac{5}{x}}$$

#

So you're dividing 9/11 by 6

#

Dividing a number means multiplying by it's reciprocal

#

Which means you are multiplying 9/11 by 1/6

#

Which is 9/66

#

And that's where 66 comes from.

Why do I get 0.136 or is that just solving it

spark slate
#

And your answer is wrong if you get 0.136

sinful lantern
#

9/11/6 gives me 0.136

spark slate
#

Of the solution

sinful lantern
#

Ok i get the ending-2.5

spark slate
#

5lne/ln(9/66)

#

Yes that's correct

sinful lantern
#

Just the 66 part confused me

spark slate
#

Even in that solution they didn't do that

👍

#

So you would always leave as fraction for this type of Q?

#

I would always leave it a fraction for any question

#

Fraction is more easier to work with

#

This is not even a type of question

#

You divide 6 because you needed to get rid of 6 on the right side of equation so that you could isolate e^(5/x)

#

More like a type of work
