I thought sqrt(8/3) was clear enough. What math principle requires you to go any further? Sometimes these math problems are just an exercise in "see how much more clever i am"

@russelllomando8460 9 месяцев назад

great prob. you simplified WAY easier than i did. thanks for the lesson.

11:32 The irrational pi or 2pi is sometimes a divisor.

Dude, you can make equations look simple and solvable. Then you reveal that is not the case unless you know the applicable rules. Then you reveal the rules as you solve the problem. This works for me! You get two tubes of brylcreem for your 50's doo along with 2 plastic combs in case one breaks due to hairspray interference. You are awesome!

Thanks for the lesson, RU-vid Math Man.

@thomasmaughan4798 8 месяцев назад

Great refresher! Early simplification made a huge difference; I multiplied the numerators and then the denominators giving 56/21 which is correct but not very useful. It simplifies to 8/3.

@MasterofDoom2006 9 месяцев назад

I got to the problem solution. I never really understood, why it is necessary to remove a square root out of the denominator, but thanks to your explanation it finally clicked, why this must be done! :)

@colinmaharaj 8 месяцев назад

I went a bit further, so, root of 4 * 2 / 3 is 2 V(2/3) ( I use V as root). Now 2/3 is 0.666 which I approx to 0.64 and the root of that is 0.8 so I go a little further and say 0.805 or something so the answer is 2.805 (I haven't used the calculator yet)

I ended up with 2 × (sqrt 2/3).

@thenakedtruth0205 9 месяцев назад

sqrt of 4/7 x sqrt 14/3 simplified to combined 4/1 X 2/3 ~ sqrt of {8/3}? and i wonder...

I've taught advanced math for 42 years. Your method might be correct but there is an easier way to find the final product.

@davew.5199 8 месяцев назад

This doesn't reault in an exact number. So it's not a good challenge.

@ellentronicmistress4969 8 месяцев назад

It's exactly why it is a good challenge: maths isn't always tidy.

@rustylugnut755 9 месяцев назад

Decimal places in Physics and hand grenades is close enough. But forgetting to rationalize the irrational denominator makes it a complete fail in Math. Bummer. Bad habits have crept into my math over years of engineering.

@rodrodrigues5402 8 месяцев назад

In one of these steps you haVe a 7 in the numerator. That is not correct.

When I went to school, we got NO part credit! it was right or wrong.

@derekborkent2899 9 месяцев назад

The square root of 8/3 = 2.63... in decimals, but your answer of 2 × the square root of 2÷3= .94... did I miss something?

@markprange2430 9 месяцев назад

They each equal 1.63....

@TheSimCaptain 9 месяцев назад

But apparently, the numerator can contain an irrational number.

@ellentronicmistress4969 8 месяцев назад

@@TheSimCaptain Yes it's considered more acceptable. I think it's a throwback to a time before calculators when it was just easier to work with irrational numbers as numerators rather than denominators. Someone might correct me though.

@olenfersoi8887 8 месяцев назад

I agree with others...Why not just take sqrt of (8/3) Answer is 1.63 and less steps than shown.

@ellentronicmistress4969 8 месяцев назад

In a GCSE exam in the UK you'd be expected to know how to express the answer as a fraction with surds. I'm not sure, but I assume that's the point here too?

@tschantz 8 месяцев назад

That is how I’d punch it into a calculator, yeah. But technically sqrt(8/3) is in improper form as there’s a square root being applied to the denominator.

square root of 8/3

@jamesharmon4994 9 месяцев назад

This equals radical (4 * 2/3). Pull the radical 4 out as 2, leaving 2 * radical (2/3). This is equal to 2 * (radical(2) / radical (3)). This equals (2 * radical (2)) / radical (3). Multiply top and bottom by radical (3) to "rationalize" the denominator gives you (2 * radical(2) * radical (3)) / 3. Then simplify this to (2 * radical (6)) / 3.
