Thank you for giving me 7/10. I was tougher on myself as I would have given me 50% for coming up with 13 radical 5/radical 6 as my answer. ;)

I wonder if you would get the same answer if you looked at Square Root Tables.I am sure you would.❤️

@mylittlepitbull3143 7 месяцев назад

I get them all right. Well, 97th percentile in math on my SAT scores

@SDon-wn8xb 6 месяцев назад

Oh, no! The statement at 10:18 is wrong. You can multiply radicals with the same radicands even if they have different indexes. In this instance, (7)^(1/3) x (7)^(1/2) = (7)^(5/6).

I came up with (2 × sqrt 3 × 13 × sqrt 5)/6.

@aryusure1943 7 месяцев назад

Multiplying my result by radical 6/radical 6. :( Indeed, these reflexes come with practice.

@charlesmitchell5841 7 месяцев назад

13sqrt5/sqrt6

@olenfersoi8887 7 месяцев назад

The problem here is that without a calculator you don't get an actual number whether or not you simplify this.

@tomtke7351 7 месяцев назад

ya kno... 13/6 × sqrt(3) isn't very useful to a carpenter, huh?

I taught math at a community college for over 20 years. If any of my students used a calculator on this problem I would have marked it wrong. If the problem asked for a decimal approximation instead of the exact answer it would have specified that. And anybody who thinks (13sqrt30)/6 isn't an actual number had no understanding of the concept of number.

@darrylschultz9395 7 месяцев назад

Why not complete the 13/30÷6? Which is approx 13/5.477÷6, which is approx 11.9!

@tichaonamugabe7107 6 месяцев назад

Because that is the exact value. It's better that way. If the question asked you to round your answer to a certain number of decimal places or significant figures then you'd do that, otherwise leave it in this form, as it's the exact value.
