## rannsan 3 years ago Divide and simplify. Assume that all variables represent nonnegative numbers: √(16/36) =

1. Harkirat

divide both numerator and denominator by 4 and see what you get...then proceed further

2. rannsan

4 and 9

3. rannsan

the common denominator is 4

4. Harkirat

now use the rule $\sqrt{\frac{ m }{ n }}=\frac{ \sqrt{m} }{ \sqrt{n} }$

5. Harkirat

friends pls do not give out the answer...

6. 2le

What I find helpful when I do square roots is to write the prime factors and group up pairs. $\frac{16}{36}=\frac{2*2*2*2}{2*2*3*3}=$

7. Harkirat

let them learn

8. rannsan

That was me, I am trying to learn this

9. rannsan

I do not understand the rule

10. Harkirat

ok by dividing both numerator and denominator by 4 you got 4 and 9

11. rannsan

yes I did

12. Harkirat

apply the rule on $\sqrt{\frac{ 4 }{ 9}}=??$

13. Harkirat

carefully look at the rule..

14. rannsan

4 will not equally divide by 9 so that is it simplified

15. Harkirat

yes you cant simplify any further so apply the rule

16. rannsan

then it cannot be squared. I am not sure of the rule you are talking about.

17. Harkirat

$\sqrt{\frac{ 16 }{ 36 }}=\sqrt{\frac{ 4 }{ 9 }}=\frac{ \sqrt{4} }{ \sqrt{9} }$

18. Harkirat

can u do the final step now???

19. rannsan

yes thank you

20. Harkirat

by the way, the final answer is 2 --- 3

21. rannsan

LOL I already figured tha tout.

22. Harkirat

good for you....☺
