How to Solve Logs with any base on the Texas Instruments TI-30X iis Calculator

[@HannahRULES]

TYSM oh my gosh, I was racking my brain in AP chem trying to figure out how to use natural logs. You’re a real live saver, thank you I’d probably fail chem as a sophomore with you. Love your content!!! ❤

[@HDCalcs]

You're very welcome! I know how it feels to be the student in theses situations, that's why I made these videos. Thanks for the support and good luck with your classes this year!

[@alexandramaderamatos2076]

love how straight to the point you are

[@HDCalcs]

Thanks Alex! I really do try to make these videos as quick and clear as I can.

[@mtutoriales]

Thank you so much sir! I was breaking my mind in class trying to find out how to write the base in the calculator.

[@HDCalcs]

You're welcome! It's a great trick, as long as you can remember it!

[@abishekraju4521]

4 years later, still as simple and relevant as ever.

[@lcg6738]

Saved my life right before my exam tomorrow. Thank you!

[@HDCalcs]

You're welcome! I hope your exam went well!

[@astraleopard6946]

Wasn’t paying attention in class when my teacher taught us how to change log bases in a calculator.. whatever way he taught, this is probably way easier, thanks

[@HDCalcs]

I'm glad to hear this is helpful, good luck in math this year!

[@camrynames3361]

Thank you!!! Saved me before my exam

[@HDCalcs]

You're welcome! Good luck on your exam!

[@absolutelymassive]

Couldn't find another video that explained this clearly and quickly. Thank you

[@HDCalcs]

You're very welcome! thanks for the feedback!

[@staceya1717]

Thank you! I am so grateful for people who take the time to make videos like this!

[@HDCalcs]

You are very welcome! It wasn't too long ago that I was a student trying to figure these things out!

[@GermanTopGameTV]

Thank you. I once knew how to do this on this calculator and forgot. It's kinda stupid that you cannot simply set a base yourself. I'm glad they changed that on later models

[@HDCalcs]

It's definitely a nice function to have!

[@jpgrennan]

Thank you!! I have my math 111 final today and we’re only allowed a scientific calculator, this is going to save me!

[@HDCalcs]

You're Welcome! Good luck on your final exam!

[@tielaph4182]

Thank you so much! You are making algebra just a little bit easier

[@HDCalcs]

You're welcome, I know how tough it can be!

[@thisagain100]

Thank you, it's been years since I had to do this and this explanation was super quick and helpful!

[@HDCalcs]

I know how frustrating it can be to come back to a subject after a long time, I'm glad this helped!

[@alinamulyar]

Thanks for the video. Short and to the point! It'll help me pass the ACT test.

[@HDCalcs]

You're very welcome, good luck on your ACT test!

[@andresalvaradolizano3838]

Thanks a lot, I got my final in an hour and was freaking out

[@shortiebop01]

Thank you for taking the time to do this! I had no idea what I was going to do! 🥰🥰🥰🥰🥰

[@linneamai244]

Thank you so much! My teacher didn't have time to explain this and I was totally stuck.

[@HDCalcs]

You're welcome Linnea, I'm glad this was helpful. The change of base can be a little confusing if you don't actually see someone doing it.

[@snigdharoy1938]

This was really Helpful 😊

[@HDCalcs]

That's great to hear, thanks for the feedback!

[@hakimizohal5308]

THANK YOU! This was really helpful!

You're welcome! I'm happy to hear this helped!

[@cassies1477]

Thank you so much, I was losing it trying to figure this out for my class!

[@HDCalcs]

You're very welcome! good luck with your classes!

[@alexhawkins1795]

You, my good friend, are a life saver! 😉👍

[@HDCalcs]

Glad to help!

[@scratchpad7954]

+HP Calcs Thank heaven I have found your video again! Last semester at Salt Lake Community College (Fall 2018), I was in Math 0980 and they had a unit (I forget which module it was in) where we needed to find logarithms. Luckily, as I remember, most of the logs were of base 10 and natural logs (of base e), but there were a few where we needed to find a different base. This semester (Spring 2019), Math 1010 has a unit in Module 8.3 where we are revisiting this.

[@HDCalcs]

It's great to hear that this helped! Good luck this semester!

[@scratchpad7954]

@@HDCalcs Thank you so much! I will also need as many blessings of luck as possible for Math 1050 this next semester coming up (Spring 2021). I tried it for this last semester (Fall 2020), but it turned out that I didn't have quite enough background this year for it as I ended up getting a B- but it was just barely short enough that departmental policy gave me a C+. I had to take a year off from math as I didn't feel very comfortable retrying it until now.

[@AtinDalkoness]

Super helpful, thank you. It is not intuitive how exactly to put logs into a calculator.

How would you do f(x)=3^(x-7) and g(x)=2log(2x)

[@princetonshot]

IT DOESN'T LET ME PRESS LOG FIRST. IT SAYS ERROR IF I PRESS LOG FIRST

[@HDCalcs]

No worries, when you have so many keys in front of you it's easy to miss a specific one!
