example?

2. anonymous

$D= SQRT* 3(1450) OVER 2$

3. anonymous

It's a word problem. it is a principle of radical that is over the 3h and 2 fraction. h=1450

4. anonymous

$\sqrt[3]{\frac{1450}{2}}$

5. anonymous

no

6. anonymous

is it a square root or a cube root?

7. anonymous

d=sqrt* 3H over 2

8. anonymous

square root--the one that is longer and then splits into two smaller ones as the next step.

9. anonymous

3h and 2 is a fraction. sqrt goes over the both of them--just one. I get that you then break it down by placing two radicals over each den and num. lost on the next step

10. anonymous

$\sqrt{\frac{3\times 1450}{2}}$

11. anonymous

correct

12. anonymous

that one?

13. anonymous

and am trying to find D

14. anonymous

divide first, then take the square root

15. anonymous

so take the den of 2 and place it under D?

16. anonymous

before plugging in H=1450?

17. anonymous

yes you can divide first. you have $\frac{3\times 1450}{2}=2175$

18. anonymous

mhm

19. anonymous

would I have to square both sets of numbers?

20. anonymous

then take the square root. $\frac{\sqrt{a}}{\sqrt{b}}=\sqrt{\frac{a}{b}}$

21. anonymous

or both sides of the equal sign??

22. anonymous

if you are just trying to compute the square root of that number, no. just use a calculator

23. anonymous

okay- go one

24. anonymous

go on

25. anonymous

rationalizing denominators means something else. for example $\frac{1}{\sqrt{2}}=\frac{\sqrt{2}}{2}$

26. anonymous

but if you just want a number you can compute inside the radical and then take the square root

27. anonymous

what did you get for the answer?

28. anonymous

46.64 rounded. in radical form i got $5\sqrt{87}$

29. anonymous

30. anonymous

it is 47, but thanks any way. haha

31. anonymous

ok fine lol
