Question

algebra help

Answer 1

this would be the concept of
√3 * √3 = 3
√5 * √5 = 5
√11 * √11 = 11
get the jist?

Answer 2

yeah I see it.

Answer 3

so to simplify
\[\frac{ 5 }{ \sqrt{11} }\] multiply top and bottom by √11
so
\[\frac{ 5 }{ \sqrt{11} } * \frac{ \sqrt{11} }{ \sqrt{11} } = \frac{ 5\sqrt{11} }{ 11 }\]

Answer 4

yep :)

Answer 5

#2 would not be D....

Answer 6

multiply top and bottom by (3 + √2)
\[\frac{ 9(3+√2) }{ (3-√2)(3+√2) } = \] then distribute the top and foil the bottom

Answer 7

yep :)

Answer 8

Correct! :)

Answer 9

it's not A or B...
3√50 * √22
is like 3 * √(50*22)

Answer 10

3 * √(50*22) = 3*√1100 = 3*√100 * √11 = 3*10 * √11

Answer 11

So then D.

Answer 12

yep :)

Answer 13

I think #5 might be C.

Answer 14

C would be correct! :)

Answer 15

correct :)

Answer 16

if they just want you to put it into word then yeah :)
but if they actually want you to simplify it, you might have to do something more with that.

Answer 17

well if they want something other than √27 * √12
then √27 * √12 = √(27*12) = √324 = √4 * √81 = 2 * 9 = 18

Answer 18

i suppose so.

Answer 19

other way around for the answers :P
idk ALL of my perfect squares so
http://www.miniwebtool.com/square-numbers-list/?to=1000

from there you can see that the squared numbers Do alternate between even and odd

and then if you look down enough,
the square root of 1089 is 33
and 33 is not a prime number

Answer 20

yep :)

Answer 21

Yay! Thank you! Are you still available to help? I still have to complete questions that are similar to what you've helped with before. You'll remember when you see them.

Answer 22

I still have 2 hours ;)

Answer 23

bleh, you're starting to learn stuff now that I'm starting to really not remember >,<
intervals between y's as x goes up 1
1, 3, 5, 9 which would mean that it is a parabola (ie x^2 equation)
when x = 0 , y=0
so it represents the parent function y = x^2
so when x = 10 y = (10)^2

Answer 24

it you don't understand it this way, I can explain it another way if you'd like

Answer 25

sure I'll see it the other way

Answer 26

it would kinda be a longer version of the previous idea
y goes up like 0 , 1, 4, 9

see how that works? so if you continue it that way....
