Question

I need help!!!

Answer 1

Go on. :3

Answer 2

√20x^13y^5/5xy^7
a. √4x^12/y^2
b. 2x^6/y
c. 2√x^12/y^2
d. 2x^6y

Answer 3

is the whole equation under the square root?

Answer 4

\[√20x^13y^5/5xy^7 \] is this how it looks????

Answer 5

Yes.

Answer 6

If you want me to explain I will :)

Answer 7

yes please!

Answer 8

alright, let's do the top first

Answer 9

√20x13y5

the square root of 20 is \[2\sqrt{5}\]

Answer 10

so we have \[2\sqrt{5}\] and then the square root of x^13 is \[x^{6}\sqrt{x}\] the square root of y^5 is equal to\[y ^{2}\sqrt{y}\]
Does this all make sense so far?

Answer 11

yes

Answer 12

so the top looks like\[2x ^{6}y ^{2}\sqrt{5xy}\]

Answer 13

the bottom is 5xy^7
the 5x cannot be simplified but the y^7 becomes \[y ^{3}\sqrt{y}\]

Answer 14

so then the bottom is \[y ^{3}\sqrt{5xy}\]

Answer 15

combine the top and bottom and you can factor out the \[\sqrt{5xy}\] and a \[y ^{2}\]

Answer 16

this leaves you with 2x^6/y which is your answer :)

Answer 17

let me know if you have questions
