You can just type it on your keyboard. Or if you don't like it, it's on the left hand side which in your meaning right hand side.

We have always given a meaning to a symbol. So this is not a question????? I am more confused. This is a question but this is not a question. AAARRRRGGGGGHHHH. My head feels like being heated!!

Better explanation about the 2nd question.

If I wrote 10, and you think it's 10, but I am thinking that it's 2. Then I wrote 10 + 10 = 100. So you say it's wrong, but I say it's correct. So is maths really a thing? I am so confused but that's me who came up with the question.

$\color{blue}\dfrac{2}{\sqrt5}\\\color{blue}=\dfrac{2}{\sqrt{5}}\times\dfrac{\sqrt5}{\sqrt5}\\ \color{blue}=\dfrac{2\sqrt5}{5}$

Actually this process is called rationalization not simplification.

Credit: Guest #1 and me for a clearer LaTeX presentation.

logx(x+1)-log2=0-->log(x(x+1)/2)=0

$\color{aqua}\boxed{\color{red}\log a - \log b = \log \dfrac{a}{b}}$

${\color{aqua}\text{So that }}\color{aqua}\log x(x+1)-log2 = \log \dfrac{x(x+1)}2$

$\dfrac{6}{4x^2}+\dfrac{2}{5x}\\=\dfrac{3}{2x^2}+\dfrac{2}{5x}\\=\dfrac{15+4x}{10x^2}$

$32 \times 12\mbox{%}$

$= 32 \times \dfrac{12}{100}$

$=\dfrac{384}{100}$

$= 3.84$

Same as Mellie's answer. 

Hi Mellie, this is the first time I see you active in the Forum. :D

I am going to share 2 LaTeX commands which make you spend less time spacing.

I found it this myself. \text{}

It does $\text{I am Max}$ Latex command: \text{I am Max}

I think this does the same thing and I first saw it from a reply from Melody. \mbox{}

It does $\mbox{I am Max}$ Latex command: \mbox{I am Max}

Post your questions :D I am willing to teach you.

$10^{2.3}\\ = 10^{\frac{23}{10}} = \sqrt[10]{10^{23}}$

Exact value. 

Melody's approximation is good. This calculator really helps a lot.
