Question 186518: HELP ME PLEASE...
I dont really undersatnd radicals.... how do you solve them.
k I think this is right... the problem was radical 44 and I got 11 radical 4.
But I need help with these problems.....
radical 48
radical 200
1/2 radical 112
radical 2 * radical 8
and problems like these....
radical 7/9
2 radical 5/4
2 radical 10/2
8 radical 13/9
4 radical 16/4
5 radical 6/2
and problems like....
radical 32 over radical 25
radical 49 over radical 4
radical 9 over radical 4
radical 64 over radical 16
and problems like these...
1/2 radical 32 * radical 2
radical 9 * 4 radical 25
radical 7 * radical 18 over radical 2
radical 10 * radical 16 all over radical 5
K i know that these will take up a lot of time to explain but I really need your help. If you dont want to do all these problems then dont but it would help me out tons. These are only like half of my home work please please help me thanks so much!!!!

But I need help with these problems
------------------
I assume you're asked to simplify.
radical 48
sqrt(48) = sqrt(16)*sqrt(3) 48 = 16*3, so you can separate them
sqrt(48) = 4sqrt(3) sqrt(16) = 4
---------------------------
radical 200
Same as above.
sqrt(200) = sqrt(100)*sqrt(2)
= 10sqrt(2)
----------------
1/2 radical 112
= 1/2 * sqrt(16)sqrt(7)
= 2sqrt(7)
--------------
radical 2 * radical 8
=sqrt(16) 16 = 8 times 2
= 4
-----------
and problems like these....
radical 7/9
=sqrt(7)/sqrt(9)
=sqrt(7)/3
---------------
2 radical 5/4
2 radical 10/2 = 2sqrt(5)
--------------
8 radical 13/9
4 radical 16/4
5 radical 6/2
and problems like....
radical 32 over radical 25
radical 49 over radical 4
sqrt(49)/sqrt(4) = 7/2 ??? What else could it be?
---------------------
radical 9 over radical 4
radical 64 over radical 16
and problems like these...
1/2 radical 32 * radical 2
radical 9 * 4 radical 25
radical 7 * radical 18 over radical 2
radical 10 * radical 16 all over radical 5
---------------
