No need to lengthen procedure Simply use log table for log 18 and log 6

That's what I was thinking as well because he used a calculator anyway.

You solved and narrated it such a way that even s child can understand it.Thank you.

Since you are using a calculator, why not simply use x=log(18)/log(6) and be done with this really super boring problem?

When I was obtaining a degree in electrical engineering back in the mid 1960s, pocket calculators didn't exist. My Post slide rule effectively added log2 and log3 to get log6, accurate to about three digits if you hadn't dropped it beforehand and you had good eyesight. Today, what professor or boss in their right mind would ever say, "No, we don't use calculators here, only pencil and paper or your slide rule if your dog hasn't chewed it up."

While I solved x = log18/log6, your method better shows the relationship of Base (6), Ans (18) and Exp (x). Good old Bacon And Eggs (BAE). Nice job.

Well explained for those who need to know how to simplify log equations. Of course, when these are embedded in much larger or more complex equations we may prefer to keep the the simplified logs until the very end rather than approximate values too early. Great explanation as I said.

I got log6(18). In my opinion you should only approximate at the end, when you have the exact solution.

You are real lecturer😊

Nice Explaination❤

Make your solution simple…if you are taking the exam in Math and time is limited you will not pass the exam.

@@kankri99 u dont understand...mind this, if u r a teacher with so many students who are slow learner plenty of them will fail...they need an approach a step by step solutions to problems so may for them to understand. And later on you may teach them with short cuts to improve their speed solving problems.

Once the calculation has reached the point of X log 6 = 18 the whole process can be greatly simplified for the sake of instruction efficiency. Students need to be taught simplification to reduce chance of error and time spent during exams. X log 6 = 18 = 6 * 3 X log 6 = log 6 + log 3 Note: multiplication of two numbers m and n is addition of the log form; log(m) + log(n) X = (log 6/log 6) + (log 3 / log 6) Note: {log 6 = log 2 + log 3 = 0.3010 + 0.4771 = 0.7782} but no need to calculate log 6 in terms of log 2 and log 3 X = 1 + (0.4771 / 0.7782) = 1 + 0.6131 = 1.6131

Why so many steps. After taking log on both sides , write x interms of ratio of log18 : log 6 , then from log table substitute the values for log18 & log 6, then that is x . Simplify by dividing.

It's a good teaching video. Technically though, once he put in truncated trancendental numbers, the equals sign should have been replaced with the symbol thtat means 'approximately equal."

Those who know long a d how to see the log table can solve the problem easily. My question is do the modern students learn how to use log table?

This problem is a heavy LOG Just can’t handle it

These are good videos, but you should really try to condense them. Some of the basic intermediary steps can be eliminated for this video. Most of us know how to divide fractions and multiply numbers. Make the videos only about 2 to 3 minutes long.

Quite an interesting video.

Thanks

The explanation is not only lengthy. It is not accurate. The values for the various logs are not finite. But of log2 and log 3 I still remember from my school 60 years ago.

log 6 is better in the factoring. But not necessary to use log 2 and log 3.

Just do log 18 ÷ log 6

How is this a Maths Olympiad question? It is easy. I thought there was going to be some trick but there is nothing original.

Nice video sir 👍

How can a maths Olympiad examee be allowed calculator ??

Log18 on base 6 is answer.

a^x = b => x = logb/loga

Why can't we just find the value of (log18)/(log6) by calculator?

@GaryBricaultLive

3 ай бұрын

It fits a more standard solution method to break the 18 into 6 * 3 first. Then (log 6/ log 6) + (log 3/log 6) will evaluate to 1 + (log 3/log 6). Either way the log values are found with a table or calculator.

Может быть просто ученикам пользоваться калькуляторами, которые всё считают.. Ну бред численно так выводить

Wtf is log6 and log18? Sounds like error.

Sir, You could solve this using a much faster and easier way. In my view, you even do not know the basics of maths and logarithms.

This is good timepass but useless. I learnt trigonometry, calculus, logarithm which have no practical value. 8th standard mathematics is sufficient in profession. Rather we should be taught MS office, basic program in Java. Thank you
