# Greater than sign
A symbol that expresses the comparison of a big quantity with small quantity is called greater-than sign.
## Introduction
The greater-than sign is a symbol in mathematics. it is mainly used to express an inequality between two quantities by comparison.
The greater-than sign is symbolically writt... | |

• Quantum hypothesis testing is one of the most basic tasks in quantum information theory and has fundamental links with quantum communication and estimation theory. In this paper, we establish a formula that characterizes the decay rate of the minimal Type-II error probability in a quantum hypothes... | |

# How do you simplify 4 sqrt x^2?
##### 1 Answer
Sep 18, 2015
$4 \sqrt{{x}^{2}} = 4 | x |$
Since the x under the root is a square, it can come out. But since everything that comes out of a root must be 0 or positive, the absolute value bar must be there.
If we know that $x \ge 0$ you can ditch the bar. | |
# Make glossary defined terms bold
I have defined a lot of terms with the glossaries package and use them in my text with the \gls{} command. However, I'd like terms called with \gls{} to appear bold, so people know that it is a term defined in the glossary. What command do I have to renew and how to achieve this?

# Finding number of don't care conditions
I'm new to these forums and have very little background in electrical engineering.
I'm trying to figure out the number of "don't care conditions" based on an input of two numbers, each 0-9, for designing a digital system to implement the multiplication table. The output would... | |
# Effective Mordell
I am Pierre MATSUMI. Could you please teach me what is effective Mordell.
Assume that f(X,Y) = 0 which defines smooth affine curve with genus > 1, and that there will be the solution X=n/m, Y=n'/m' in rational number Q. Then,

## nanoVNA – measure common mode choke – it is not all that hard!
It seems that lots of hams find measuring the impedance of a common mode choke a challenge… perhaps a result of online expert’s guidance?
