Question

what is the degree of the monomial?
^7x^8
7
8
15
56

Answer 1

arent you missing something there?, the starting ^7 makes no sense alone...

Answer 2

thats what i thought but no thats how the answer there is shown. maybe its 7x8 ? I'm not really sure.

Answer 3

mmm.. anyway, the degree is the value of the exponent of the x power... so in this case we have "x to the _____ power"

Answer 4

so snice there both x i believe i should add them? which is 15?

Answer 5

but there is only one x, right? i read ^7x^8, which reads as "something missing to the 7th power times x to the eigth power"

Answer 6

yeah theres only one x :o so does that mean the x only belongs to 8?

Answer 7

yeap, x is powered to 8, so the degree should be 8 :)

Answer 8

thank you so much! c: can you help me with a few more questions?

Answer 9

lets see if i can... shoot! :D

Answer 10

Solve the equation by completing the square.Round to the nearest hundredth if necessary.
x^2+2x=8
x=2,4
x=-2,4
x=2,-4
x=-2,-4

Answer 11

ok! do you recall what completing squares is?

Answer 12

I don't believe I do

Answer 13

and I have a question about the first question I asked so i multiply 7*8? right?

Answer 14

it consists in taking the equation to something like this:
\[(x-a)^2 = b\]
so it is easier to solve

Answer 15

in the first one, it is not clear what the 7 is there for... if we assume it is not in the power of the x, then we dont need it for the answer

Answer 16

oh okay thank you!

Answer 17

and for the 2nd question is the answer a?:o

Answer 18

i found it is the third one... 2,-4

Answer 19

thank you! c: i have a few more is that alright?
