But how did we get negatives I’m confused

joshua. :

Log(4)(0.25)💁🏾‍♂️

Yones🇯🇴🇵🇸 :

Logs are a thing…

___morphh :

How did the x turn to a negative value?

vinnybillywilly :

ok the last minute with the minus.... didn't get it.

lala :

But cant we just write 4^x=4^-1?

️ :

u lost me when u changed the decimal to a fraction

Venice b1tch :

I would just make it 1/4 and then that would be 4^x=4^-1 so that would be x=-1

⍣ 𝑅𝒶𝓅𝒽𝒶 ೋ :

Where the flip did the negative come frim

ayyu :

x = -1

ꉂ🪷`˖ ⋮ alex ୭ . :

wait what . You lost me at negative

lem9r :

You can take logs of both sides it’s easier

𝓐𝓻𝓲𝓪𝓭𝓷𝓪 :

It would be easier if you just invert the four and have 4^x=4^-1, the answer is x=-1

𝓡𝓸𝓼𝓪𝓵𝓲𝓷𝓪 :

Took me 5seconds 🙂‍↕️

𝔥𝔞𝔯𝔪𝔬𝔫𝔶 🎚️ :

got it in the first 2 seconds lol

greenmore1969 :

1/4 = 4⁰/4¹ = 4⁰⁻¹ = 4⁻¹, hence, 4^x=4⁻¹, x=-1.

_hei.emma_ :

:0… my god i hate math

RIBBIT #1 LOVER :

I already figured it out in an easier way before watching the video😭🙏I noticed that 0.25 is a quarter of 1 (which a quarter means 4) and I noticed that it was 4 to the power of x, so I just thought carefully and realised that 4 0.25s would make 1 so it would have to be 4 to the power of -1. Sorry if I worded it badly

nintendorewind3 :

Get rid of the 4 to get x on its own its log to the base 4 of 0.25 and it gives -1 in your calculator

footyalek :

She severely overcomplicated that

tru2hilarious :

My head hurt
