You set the denominator equal to 0

#

Then it’s logarithm stuff and i’m lost there

#

dull citrus You set the denominator equal to 0

Because of course the denominator can’t equal 0 so there would be discontinuities there

dull citrus Then it’s logarithm stuff and i’m lost there

Move -e^(…) to the other side, then take ln of both sides

Could you explain in more detail?

#

We are solving $8-e^{5-4x}=0$

#

The first step to solve this would be move the e to the other side

#

$8=e^{5-4x}$

#

From here how can we get rid of the e and move the exponent down. The answer is with logarithms

#

I still cant figure it out

#

Says my answer is wrong

#

calm zenith Feb 5, 2024, 5:09 AM

#

Hmm should be correct

#

Maybe error in the way your entering it

dull citrus Feb 5, 2024, 5:11 AM

#

Looks correct to me

#

Maybe im missing a solution

#

Somehow

#

I think it wants more decimal places

#

But the calculator doesn’t show all

#

Im using desmos

#

Is there a way

calm zenith Feb 5, 2024, 5:14 AM

#

It probably wants the exact answer

#

Are you able to type it in exactly? I believe you can since ive used that b4

dull citrus Feb 5, 2024, 5:15 AM

#

I dont think so because i did a practice a similar problem option and i solved it the same way

#

Then it showed me the answer and steps

#

My answer was right just not enough decimal places

#

But thats dumb

#

calm zenith Feb 5, 2024, 5:16 AM

#

I do not think thats the issue. If they wanted you to right the decimal expansion they would tell you how many decimals to use

dull citrus Feb 5, 2024, 5:16 AM

#

See what i mean

#

Ill do the exact answer

#

I have 2 attempts left

calm zenith Feb 5, 2024, 5:17 AM

#

Yeah try that

#

I am 99.9% sure thats what they want

dull citrus Feb 5, 2024, 5:17 AM

#

Thatd be the only thing that makes sense

#

It was

calm zenith Feb 5, 2024, 5:17 AM

#

In that website usually when you need to type in rounded answers the box is smaller and a wider rectangle shape

Imbeciles

calm zenith Feb 5, 2024, 5:18 AM

#

Yeah for the future you should always do exact answer unless stated otherwise

dull citrus Feb 5, 2024, 5:18 AM

#

Why show me the exact decimal answer in the practice problem then want the exact answer

calm zenith Feb 5, 2024, 5:18 AM

#

Yeah that is kinda misleading

dull citrus Feb 5, 2024, 5:18 AM

#

But thank you i spent an hour fondling my brain because of this

#

.solved
