Question

What is the 3rd term when 2y2 + 3y4 − 5y + 6y3 is arranged in descending order?
A.) 2y2
B.) 3y4
C.) −5y
D.) 6y3

Answer 1

are you able to identify the exponents here?

Answer 2

Im really lost on this i dont even know how to start

Answer 3

you have this as the problem

\[\Large 2y^2 + 3y^4 - 5y + 6y^3\]

right?

Answer 4

correct

Answer 5

that is the same as \[\Large 2y^2 + 3y^4 - 5y^1 + 6y^3\]

Answer 6

notice how 5y changed to 5y^1

Answer 7

I'm marking the exponents in red

\[\Large 2y^{\color{red}2} + 3y^{\color{red}4} - 5y^{\color{red}1} + 6y^{\color{red}3}\]

Answer 8

yes

Answer 9

when they say "descending order", they want the exponents to decrease (ie count down)

Answer 10

what is the largest exponent?

Answer 11

4

Answer 12

so 3y^4 comes first

the next largest exponent is 3, so 6y^3 comes next

and so on

Answer 13

what do you get when you arrange the terms in descending order?

Answer 14

so after i do that what should i do?

Answer 15

can you write out the terms for me? when you've sorted them in descending order

Answer 16

3y^4 3y^4 6y^3 5^y1

Answer 17

or wait

Answer 18

3y^4 6y^3 2y^2 5y^1

Answer 19

very good

Answer 20

first term: 3y^4

second term: 6y^3

third term: 2y^2

fourth term: 5y^1

Answer 21

okay got it now what

Answer 22

they want the third term and I listed it above

Answer 23

and I listed it based off what you wrote

Answer 24

so you're done at this point pretty much

you just list that third term

Answer 25

so whats the anwser then

Answer 26
