Rewrite the expression in lowest terms with the radical in the numerator...?

Question

12/√13

Not sure if I wrote it correctly. Let me know if I didn't. Thanks for any help with the problem

Answer 1

12 / √13 =

12√13 / √13√13 =

12√13 / √169

12√13 / 13

- - - - - - -s-

Answer 2

If you multiply something by one, you get the same thing that you started with right? So if you have 12/√13, in order to get rid of the √, you can multiply 12/√13 by √13/√13 (the same thing as one) and you get 12√13 /13

Answer 3

Hi,

If there is only one term on the bottom with a square root, multiply the numerator and denominator both by that same square root. Realize that when you multiply a square root times itself you get the number inside the radical as your answer. That is, sqrt(5)*sqrt(5) = 5)

In your problem

12
----------- =
sqrt(13)

12*sqrt(13)
----------------------- =
sqrt(13)*sqrt(13)

12*sqrt(13)
----------- =
13

If those numbers outside the radical could be divided, you would divide or reduce them. If the radical could be simplified, you'd have to do that too.

I hope that helps!! :-)

Answer 4

lol, simplify by multiplying the numerator + demoninator by sqrt(13)

then you get 12sqrt(13)/13

=P

Answer 5

12 √13 12√13
---- * ----- = -----------
√13 √13 13


answer: (12√13)/13

Answer 6

12/sqrt(13)

multiply top and bottom by sqrt(13)

(12sqrt(13))/13 or (12/13)sqrt(13)
