Question

-18x^2y^-1/2 over 6x^-1/5y....Simplify and express the answer with positive exponents. Evaluate numerical expressions.

Answer 1

do you need help in learning how to do these?

Answer 2

yes i do

Answer 3

when you write the expression as a fraction, the letters with the negative powers ...if they are above the viculum they go below and the sign changes in their pwer

Answer 4

Ok I understand that part

Answer 5

if they are below the vinculum you take them aboce and change the sign in their powers

Answer 6

If you end up with ...eg...y^2 x y^1/2...you add the powers

Answer 7

Ok, add them...Gotcha

Answer 8

I can lead you through this question if you wish

Answer 9

Yes if you could please

Answer 10

Write the whole thing as numerator over denominator

Answer 11

\[x^2/x^{-1/5}=x^2x^{1/5}=x^{11/5}\]

Answer 12

did it

Answer 13

-18/6= -3/1 = -3

Answer 14

6 can go into the numbers 18 and 6...cancel

Answer 15

cancel them out?

Answer 16

\[y ^{-1/2}/y = y ^{1/2}y =y ^{3/2}\]

Answer 17

you will get -3 on top and the 6 at the bottom cancels

Answer 18

alright ok

Answer 19

Notice x has a negative power underneath

Answer 20

oh opss....
\[y^{-1/2}/y= 1/y^{1/2}y= 1/y^{3/2}\]

Answer 21

so in the end it's\[-3x^{11/5}/y^{3/2}\]

Answer 22

i notice it

Answer 23

carry x^-1/5 on top...it becomes x^1/5 and it is multiplied by x^2

Answer 24

I am getting the hang of this, I think that I get it now

Answer 25

The y^-1/2 goes to the bottom

Answer 26

u'll manage now ?
