(1 point)
A. 245y²w³

Answer 6

sorry this is answer C

Answer 7

i dont know this question

Answer 8

HNC: Please post one question at a time. It's difficult to know which of your five questions you're referring to.

The key to solving the first problem is to look for a perfect square under the radical sign and then to separate (factor) the radical into two parts:\[\sqrt{45=}\sqrt{9}\sqrt{5}\] Is 9 a perfects quare? Is 5 a perfect square? What would you do next? What is your final answer?

Answer 9

well no 9 is not so it would be 3 and 5 is.

Answer 10

Let's back up a bit: Is 5 a perfect square?

Answer 11

umm i think it is

Answer 12

like it cant go any lower right?

Answer 13

What is the square of 1?

Answer 14

um nothing....so yes ig it can go all the way to 1

Answer 15

In math, "squaring" a number involves multiplying it by itself. What is 1*1?

Answer 16

1

Answer 17

that's better.
What are the squares of 2 and 3?

Answer 18

1

Answer 19

where did that come from? please go back to my explanation of the meaning of 'Squaring a number."

The square of 2 is ... ??

Answer 20

i had already answered that problem did i get it wrong or something? also i dont have alot of time and i really need help with the last ones that i havent answered.... 2

Answer 21

ik but i wasnt sure so i didnt put it...

Answer 22

I'm sorry, Cudi, but you have NOT answered Question 3 correctly, and you have not demonstrated that you understand what the "square" of a number is. Math is not a guessing game; you need to understand the definitions and the rules that apply. If you want to move on to the later questions, fine, but i will still expect you to invest enough time and effort so that you actually know what you 're doing. So...what do you want to do now?

Answer 23

not guess btw....but thank you still for giving me your time and effort to help me i didnt answer number 3....

Answer 24

Either you demonstrate how you obtain your answers or I must assume that you are guessing.

Answer 25

Where is the "radical expression" of Problem #5?

Answer 26

ok well for number 3. \[\sqrt{45} = \sqrt{5}*\sqrt{3} =5{\sqrt{3}}\]

Answer 27

that is how it is in my math book so my math book must b wrong then...

Answer 28

5.

Answer 29

5 is NOT a perfect square, so Sqrt(5) does not equal 5.

That's why I asked you to square the numbers 1, 2, 3, ...

sorry, I do not agree that "my math book must be wrong."

Plese decide which question you want to work on NOW.

Answer 30

3....well 15 isnt either....im looking at the book and looking at yours and looking at the problems if its not then non of them are right...its not an argument its help so help me try to figure it out please and thank you.

Answer 31

\[\sqrt{45} = \sqrt{9}*\sqrt{5} = ( ? )\sqrt{5}\]

Answer 32

ohhh omg im embarrassed now i put the wrong thing in but yes i ment the 9 in the other one...3 squared of 5

Answer 33

9 is a perfect square. What is the square root of 9?

5 is not a perfect square, so you cannot simplify Sqrt(5).

Please type out your answer to #3.

Answer 34

\[3\sqrt{5}\] the square root of 9 is 3

Answer 35

\[\sqrt{45}=\sqrt{9}\sqrt{5}=3\sqrt{5}\] perfect!

Answer 36

Which problem do you want to focus on next?

Answer 37

number 5

Answer 38

tYPE out #5 here, please, using Equation Editor.

Answer 39

ok

Answer 40

\[\sqrt{490}y ^{5} w ^{6} \]\[A. 245y ^{2} w ^{^{5}}\] \[B. 7y ^{2} w ^{3} \sqrt{10y}\]

Answer 41

not done i have a very slow computer

Answer 42

C.\[7 y ^{^{2}} w ^{3}\sqrt{10yw}\] D.\[7\sqrt{10y ^{5}} w ^{6}\]

Answer 43

ok that took 4ever but there

Answer 44

Is this the entire problem statement? \[\sqrt{490}y ^{5} w ^{6}\]

If so, you don't have to do anything with the y^5 or the w^6. Instead, focus on Sqrt(490).

There is a perfect square factor in 490. What is it?

Answer 45

49?

Answer 46

and yes that is the full statement

Answer 47

What is the square root of 49?

Answer 48

7

Answer 49

All right. Then your entire expression simplifies to \[7\sqrt{10}y^5w^6.\]

Answer 50

ok thanks again could you do one more?

Answer 51

6. Simplify the radical expression.

Answer 52

if possible?

Answer 53

type out the last problem and do as much as YOU can do by YOURSELF. Then I'll respond as appropriate.

Answer 54

ok

Answer 55

All you need to share is the expression you need to simplify. Don't bother with the answers.
