Question

Can someone please check my work on operations with radicals?

Answer 1

(1.)
√750 + √1080
25 * 30 + 36 * 30
√25 * √30 + √36 * √30
5√30 + 6√330
11√30

(2.)
√605 - √500
121 * 5 - 100 * 5
√121 * √5 - √100 * √5
11√5 - 10√5
1√5
√5

(3.)
√24 + √54
4 * 6 + 9 * 6
√4 * √6 + √9 * √6
2√6 + 3√6
-1√6

Answer 2

#3 2√6 + 3√6 = -1√6 is not correct


2√6 + 3√6 = 5√6

Answer 3

#√25 * √30 + √36 * √30

5√30 + 6√330 --> 330 typo where 30 should be

Answer 4

Oh, yes, I messed up in #3 because I forgot I was adding. haha
And I'll correct that typo too:)

Answer 5

Here it is now

(1.)
√750 + √1080
25 * 30 + 36 * 30
√25 * √30 + √36 * √30
5√30 + 6√30
11√30

(3.)
√24 + √54
4 * 6 + 9 * 6
√4 * √6 + √9 * √6
2√6 + 3√6
5√6

Answer 6

Are you turning in this work or just the answers? If you are turning in the work, there is something that needs repair in my opinion.

Answer 7

I have to turn in the work too.

Answer 8

Look at the second step on each problem.

√750 + √1080

25 * 30 + 36 * 30

It is not true that the first step and second step are equivalent

Answer 9

It should look like this:

√750 + √1080

√ ( 25 * 30) + √ (36 * 30)

Answer 10

Ok, I'll make the corrections. Thanks for your help:)

Answer 11

You are welcome.
