Simplify sqrt 48. I got 4 sqrt 3. is that correct???
:)
Mind showing how you got that? then I'd be more comfortable confirming or correcting your approach.
U R RIGHT .
That's what I got
would you please let @Death_The_Kid respond first, showing his own work? Thank you.
IM A GIRL @mathmale thanks a lot. i don't really know how i got it i was working it out and the answer just popped in my head. I wanted to use openstudy to check my answer to make sure i wasn't going crazy
IM A GIRL
Oh? Sorry indeed! :) Let me assure you that you're not going crazy. Starting with Sqrt(48), think of one or more factors of 48 that is a perfect square. For example, 4 and 16 are both factors of 48.
The most efficient way to go is to identify the largest perfect square factor of 48. What is it?
Uhm..... heh?
oh eight
i think
But, DTK, 8 isn't a perfect square, is it? If not, try again. Is 4 a perfect square? 16? 48?
jesh........
Hints: Perfect squares are: x x^2 0 0 1 1 2 4 3 9 4 16 and so on.
So: which of the following are perfect squares? 1,4,8,12, 16,48
ohhhhhhhh
4 16 48 etc?
according to the table I typed in for you, 1, 4 and 16 are perfect squares. 48 is not: Perfect squares are: x x^2 0 0 1 1 2 4 3 9 4 16 5 25 6 36 7 49 8 64
ohhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh sorryz
Hope you'll keep this for later review. Now, among 1,4, 16, which is the largest perfect square?
16
Absol. right!
Factor 16 out of 48. What do you get as the 2nd factor of 48?
Hint: 48 divided by 16 is ???
three
So Sqrt(48) can be re-written as Sqrt(16*3), right?
oh so i WAS right!
Yes, you were. And we are allowed to factor Sqrt(48) into Sqrt(16)*Sqrt(3). What is Sqrt(16)?
4
4 sqrt 3!!!!!!!!!!!!!!!!!!! YAY
And so Sqrt(16)*Sqrt(3)= ( ? )*Sqrt(3)
44444444444444444444444444444444
cool. Oh, I love it when someone else comes to an undrstanding like this!
lol are you a math teacher?
Hope to see you again on OpenStudy! Best of luck to you. MM I tutored and taught Math on and off for 43 years, in Rochester, New York.
cool!
All the best to you! Bye for now. :) MM
