good example. Want to thank you. Went to college and had to do agrebras and calculus. but have done computers since - so got rusty. I am not getting good with algrebra and better now than even on college. thank yuou did this one in my head. - one error - but not bad for in head. was darn close.
got it, great explanation, thanks.
Very good...
I wonder if you would get the same
answer if you looked at Square Root
Tables.I am sure you would.❤️
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 get them all right.
Well, 97th percentile in math on my SAT scores
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).
Multiplying my result by radical 6/radical 6. :(
Indeed, these reflexes come with practice.
I'd est 13√30/6 responsi.
I came up with (2 × sqrt 3 × 13 × sqrt 5)/6.
13√30/6
13sqrt5/sqrt6
Yep, I stopped before the last step.
Many will get this right.
I’m going with 13sqrt30/6
The problem here is that without a calculator you don't get an actual number whether or not you simplify this.
ya kno...
13/6 × sqrt(3) isn't very useful to a carpenter, huh?
@@tomtke7351The carpenter would get the wrong answer if he used a calculator typing in
13/6 . SQR(3) 😂
@@panlomito my calculator gets right answer
@@tomtke7351 You can not blame the calculator for wrong input.
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.
Why not complete the 13/30÷6? Which is approx 13/5.477÷6, which is approx 11.9!
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.
You re too confusing. Babble too much. Get to the point.
