Question

Help with 4 questions?
Kind of confused :/

1. sqrt(12) + 2^2

2. 10 - sqrt(18)

3. sqrt(15) - 1^2

4. sqrt(3) + 2

Answer 1

sqrt(12) + 2^2

what is 2^2?

Answer 2

and what are the factors of 12?

Answer 3

4

Answer 4

Well see, this is what I did.

Since 12 doesn't have two numbers multiplied by its self I just squared it in a calculator and got 3.46 basically.

Then I added 4 because 2^2 is 4.

Then I got 7.46

Did I do that right or did I do it wrong?

Answer 5

you did the steps right, the only question I have is can the answer be in decimal form?

Answer 6

like, your teacher wants it in decimal form?

Answer 7

Well the answers are

Between 7 and 8
Between 3 and 4
Between 5 and 6
and Between 2 and 3

so yeah they can be in decimal form.
Just, I got between 7 and 8 more than once?

Answer 8

if it can be in decimal answer form, then I think you did that question correct and can probably figure out the rest with out my help ^_^
but if you need help, just ask

Answer 9

I figured it out, I just made a mistake on one question xD
