Answer 4

someone plz help me figure this out

Answer 5

@aprilbarrios455

Answer 6

you might want to multiply by something then ... as per the basic lesson material

Answer 7

huh?

Answer 8

your lesson plan covers how to rationalise ... what process does it lay out for you?

Answer 9

i have to rationalize the denominator

Answer 10

and from your lesson material, how would you suggest we go about that?

Answer 11

Multiply Both Top and Bottom by a Root. Sometimes we can just multiply both top and bottom by a root: ...
Multiply Both Top and Bottom by the Conjugate. There is another special way to move a square root from the bottom of a fraction to the top ... we multiply both top and bottom by the conjugate of the denominator.
Rationalize the Denom

Answer 12

first one should be appropriate

Answer 13

sqrt(30) * sqrt(30) = 30 so i would suggest multiplying top and bottom by sqrt(30)

and simplify

Answer 14

so i would do 4 x sqr(30) and sqrt(6) x sqrt(30)

Answer 15

in general ..
\[\frac{a\sqrt b}{\sqrt c}\]
\[\frac{a\sqrt b}{\sqrt c}*\frac{\sqrt c}{\sqrt c}\]
\[\frac{a\sqrt b\sqrt c}{c}\]
\[\frac{a\sqrt {bc}}{c}\]

Answer 16

ok everything multiply by sqrt 30

Answer 17

yes, but recall that (xy)*z is NOT the same as (xz) * (yz)

Answer 18

ok so i got 24sqrt(5)

Answer 19

and 30

Answer 20

let me dbl chk that

4 sqrt(6) sqrt(30)
---------------
30



4 sqrt(180)
-----------
30


2 sqrt(180)
-----------
15


2 sqrt(9*4*5)
-----------
15


2*3*2 sqrt(5)
-----------
15


4 sqrt(5)
---------
5

Answer 21

or simply

4 sqrt(6)
-------
sqrt(30)



4 sqrt(6)
-------
sqrt(6*5)


4 sqrt(6)
-----------
sqrt(6) sqrt(5)


4
-------
sqrt(5)



4 sqrt(5)
---------
5

Answer 22

so the answer is 4sqrt 5
-----------------------------
over 5
