Question

can you help me.

[7.01] Choose the polynomial written in standard form.

x2y2 + 4x4y + 10x6

x4y2 + 4x3y5 + 10x

x7y2 + 4x3y + 10x3

x6y2 + 4x3y8 + 10x2

Answer 1

Any ideas?

Answer 2

maybe this one x4y2 + 4x3y5 + 10x

Answer 3

Why?

Answer 4

@skullpatrol can you explain this? Even if @Felicia123 gets the right answer please?

Answer 5

Do you know the definition for the standard form of a polynomial?

Answer 6

in descending order from highest to lowest so it is the third one.

Answer 7

you have to put the exponents in order. :)

Answer 8

you sure its 3

Answer 9

Yep positive

Answer 10

How do you determine which term has the highest exponents when there are multiple variables?

Answer 11

I don't know

Answer 12

Neither do I. I was asking @Maxicat or @skullpatrol - These questions have never made any sense to me.

Answer 13

oh

Answer 14

you make sure the powers are in decreasing order you have to add the exponents of the variable then decide. i know its confusing

Answer 15

yes it is lol

Answer 16

I promise the answer is the third one

Answer 17

Ok, so you add the exponents of all variables in a term to get an index number (not sure what to call it) and list the terms in descending index value.

Answer 18

Yes

Answer 19

What is the point of writing an expression or equation in this form?

Answer 20

They are called "exponents"

Answer 21

refers to the constant term in the order

Answer 22

Zero refers, sorry, screen keeps jumping all over lol

Answer 23

so why is it 3 one

Answer 24

\( x^7y^2 + 4x^3y + 10x^3\)
First term index = 7 + 2 = 9
Second term index = 3 + 1 = 4
Third term index = 3
It is in descending order according to the index value.

Answer 25

\(x^2y^2 + 4x^4y + 10x^6\)
First term index = 2 + 2 = 4
Second term index = 4 + 1 = 5
Third term index = 6
Not in descending order.

Answer 26

oh i got it now thanks
