What order do I do this in? there are no parenthesis so i am not sure?
Simplify. Express your answer in simplified radical form
square root of 48 minus square root of 3

48 ^1/2 - 3^1/2
(16 * 3 )^1/2 - 3^1/2
16^1/2 * 3^1/2 - 3^1/2
4 * 3^1/2 - 3^1/2
(4)(3^1/2) - (1)(3^1/2)
3(3^1/2)
Just so I don't confuse you I'm using ^1/2 to mean square root, so 3^1/2 means square root of 3

Reduce the root of 48 first.
(Hint: 4X12 = 48, 12= 3 x 4)
Then subtract 3^-2

You don't need ( ), sqrt(48) is one number and sqrt(3) is another. The simplification is to note the sqrt(48) can be written as sqrt(16x3) and that this can be rewritten as sqrt(16) x sqrt(3). Now, the sqrt(16) =4, so you have 4 sqrt(3). In the problem, you would have 4 sqrt(3) - sqrt(3). The sqrt(3) factors, and the result is 3 sqrt(3)

If you're not sure, you just have to make an assumption and go from there. Partial credit is better than none.
My assumption: â(48)-â(3)
= â(3)ââ(16)-â(3)
= â(3)â(â(16)-1)
= â(3)(4-1)
= 3â(3)

sqrt(48) - sqrt(3)
You need to factor a perfect square out of the 48: 16*3
sqrt(16)*sqrt(3) - sqrt(3)
= 4*sqrt(3) - sqrt(3)
==> 3*sqrt(3)
Hope that helps!

just how it says left to right when there are no () you just write out the mathematical sentence Left to right
