Okay so I have to find the square root of 5376.
If you absolutely CAN'T find that one what would 1344's be.
And it can't be a decimal it has to simplified. Like 2 then a square root symbol and then 5 (for example)

Basically, does the sqauring cancel out the square root, or does the "no negative square roots" rule still aply?

Your patient is on a dobutamine drip and it is to run at 40 mcg/kg/min. Your patient weighs 121 lbs. You have 500 mg of dobutamine in 125 cc D5W. How many cc/hour do you set the IV to run at?

My answer rounds to 65cc/hr. My instructor's answer is 33cc/hr. I am confused...Let me see what you think.

i have 200 q's to do this summer. and im stuck on these 5. i have no one to consult with except you bright and intelligent people. please help...
#1. a) evaluate (1 + i)^2, where i = Squareroot(-1)
b) prove, by mathematical induction, that (1 + i)^(4n) = - 4^n, where n € N
c) hence or otherwise, find (1+ i)^32

#3. the variables x,y,z satisfy the simultaneous equations....
x + 2y + z = k
2x + y + 4z = 6
x - 4y + 5z = 9
where k is a constant.
a) (I) show that these equations do NOT have a unique solution.
(II) find the value of k for which the equations are consistent (that is, they can be solved).
b) for this value of k, find the general solutions of these equations

#5. solve the equation l e^(2x) - ( 1/ (x+2) ) l = 2
#4. the ratio of the fifth term to the twelfth term of a sequence in an arithmetic progression is 6 / 13. If each term of this sequence is positive, and the product of the first terms and the third term is 32, find the sum of the first 100 terms
