Hence Write √600 + √54/√338 in the form √q

You may use 338 = 2 x 13^2

Thanks.

simplify the folloing by rationalising the denominator

(3+square root 2)
-------------------------
(4-square root 2)

please can you explain how you do it. cheers

For example, if you graph a standard curve from the following data:
Concentration of Solution (μg/ml)
1.0
2.0
3.0
5.0
6.0
7.0
Absorbance
0.17
0.48
0.75
1.37
1.69
1.96

What would be the absorbance of a sample whose concentration was 5.4 μg/ml. And how do you determine the answer?

The experiment observations was as follows: -
-HgClx dissolves in water to form a colourless solution.
-On adding H3PO2 a white suspension forms which rapidly turns to a grey suspension of droplets of metallic mercury.
-On further heating, the suspended droplets merge to form large drops of Hg(mercury) at the bottom of the beaker.

Several experiments was done using different masses of HgClx.

I plotted a graph of mass of Hg against mass of HgClx. Is this correct?
Also I got 0.71818 as slope(gradient) of the graph can i use it to find x in HgClx? If so how?
[Ar: Hg, 201.0: Cl, 35.5]
Thank you for any help in advance.

I have a trig question where for this right triangle, only the angles of 90, 18, and 72 degrees are given. It asks to find one of the sides. The answer is written beside the question (the answer's 1.0). Is it possible to solve this using only the angles, or does the answer have to be used?

(Sorry if the answer is really simple, I've forgotten everything from last year)
