I don't really know if these are correct because I have never had to define any of those words or know a lot of these. But some of them I am pretty sure are right. I hope I helped some. I am sorry if I didn't. But this is my best guess.
AB
It is indicated in the figure and is valid:
m AB = 49
m ABC
Angle resulting from the following subtraction:
m ABC = 360-107 = 253
m BAC
Angle resulting from the sum of the two angles shown in the figure:
m BAC = 107 + 49 = 156
m ACB
Angle resulting from the following subtraction:
m ACB = 360-49 = 311
√3√27
=√(3*27)
=√81
=9
As 9*9=81.

RULES:
√a√b=√ab
As (√a√b)²=((√a)²(√b)²)=√a√a√b√b=ab
When:
(√a√b)²=ab
√a√b=√ab
