there's actually an easier way to calculate b in the last question. if you know that 9= 3^2, and square root of 3 =3^1/2, that means 3^2 x 3^1/2, then you can just add the powers to get 3^2.5

You made a meal of that last question. I converted 9 to (3 to the power of 2) then x (3 to the power of 1/2) , so add indices to get 2+ 1/2, therefore b = 5/2. Thanks for your clear instructions on the rules to enable me to do that 😀

@SpiralDiving 3 года назад

There is a quicker solution to question at 19 minutes. Note that 3^(a+b+c) is the result of the multiplication of the three given terms. When you multiply the 3 terms they all cancel so 3^(a+b+c) =1. Hence a+b+c = 0 (because 3^0 = 1)

@TheGCSEMathsTutor 3 года назад

Very well spotted and you’re absolutely right, I wonder how complex this would be however if they didn’t sum to 1. The method I’ve applied here would ensure marks were collected on an exam paper no matter the numbers in question but you’re method is definitely a viable alternative! Also, very well explained via a RU-vid comment so I take my hat off to you 😁👏🏼👏🏼

@aims__8785 2 года назад

There's a much easier way to find what b is on the last question. Separate the 9 and sqrt(3) and make them both 3 to the power of something. So 3^1/2 = sqrt(3) and 3^3 = 9. They are both multiplying together so (3^1/2 x 3^2). Then add the powers and you get 3^5/2 so b =5/2.

@TheGCSEMathsTutor 2 года назад

Love it! 😁🙏🏼🙏🏼

@tess6484 2 года назад

@everythingtv4875 2 года назад

@MadhubalaArts 2 года назад

Last question can be done more simpler using formula 3 power a * 3 power b * 3 power c = 3 power a+b+c 3 power a * 3 power b * 3 power c = 1/9 * 9*sqrt(3) * 1/sqrt(3) => 3 power a+b+c = 1 => 3 power a+b+c = 3 power 0 => a+b+c=0

@andreabenjamin4964 Год назад

Many thanks. With the last question, I thought it was just testing your knowledge of indices rules, i.e 3a x 3b x 3c = 3a+b+c. So you multiply the 3 together and as the 9s and root 3 cancel, it works out as 1. And if 3 a+b+c = 1, then a + b - c must = 0 because any number to the power of 0 =1

@askhfbfns67589 3 года назад

17:45 for anyone who doesn't understand his method of finding out b, i know an easier way. since we know that sqrt(3) is the same as 3^1/2 and 9 si the same as 3^2, we can write it as 3^b= 3^2 * 3^1/2 now its much eaasier since we can just cut out the two 3's and add the powers and we get 2+1/2 which equals 5/2 so the answer would be b=5/2 well I hope this helped. have a good day

@nawaladawe1640 Год назад

Active recall for sciences and any humanity. What i mean by this is take a look at your specification and then make the requirements into questions for you flashcards (i recommend anki its WAYY better then quizlet and it uses active recall!) for example students must know the definition of active transport. using bbc bitesize or a revision book (both are great tbh) make an answer to that question and revise that deck of flashcards for 7 days after that search up topic questions (gcse biology movement in cells or gcse physics energy past paper questions) and some lovely people on the internet would have already compiled it for you! For maths i would recommend doing questions from a topic like algebra from corbett maths or maths genie and then the questions you got wrong or werent able to get at all just search it up on youtube like fractional indices gcse maths and you will get lots of vids doing examples and giving you questions to do at the end. Hopes this helps xx

@calcpost3641 4 года назад

Sir just wondering for the last question and for calculating b what are the indications that show we need to keep multiplying the root 3's because I dont understand how you would realise to use that in an exam

@beng5111 3 года назад

These videos are excellent ....on this one you may find an easier way to think about it to be.....write the product of the rhs of each equation to be equal to 3 to power x...simplify to give 1 equals 3 to power x.....or, alternatively, write each term as base 3 and solve the equation of the powers by adding

@sinistergaming1418 3 года назад

Just think it this way 9=3^2 And √3=3^1/2 the base is same so when u multiply the base u add the powers hence 3^2+1/2=3^5/2

Can you please help me solve this question step by step. 9( to the power of minus one half)= 27(to the power of one fourth) divided by 3(to the power of x+1)

@muneebs1123 3 года назад

9^-1/2 is equal to 3^-1. 27^1/4 is equal to 3^3/4. Because 27^1/4 is being divided on the right side, we multiply it on both sides. 9^-1/2 x 27^1/4 = 3^x+1 However we know what 9 and 27 is to the base of 3 so we rewrite it as, 3^-1 x 3^3/4 = 3^x+1 Its multiplication so the powers add to x+1, -1 + 3/4 = x+1 -1/4 = x+1 x = -5/4

He did it by seeing how many times you need to multiply it in order to get sqrt(-3) * 9. But you can also just do 3^1/2 * 3^2 and get 2.5,

try to be more clear in your speaking and explanation. Not everyone is capable of understanding a British accent

Sorry that you are struggling to understand my accent. This is the first comment that has ever mentioned this out of tens of thousands of comments so I’m quite shocked as my clarity of speaking is one of my primary goals on the channel, but my only advice to fix this would be to turn on the captions so that you have subtitles, I hope this helps! 😁🙏🏼
