The order of operations is PEMDAS which states that the operations must be evaluated in the order of Parentheses, Exponents, Multiplication and Division in order from left to right, and then Addition and Subtraction in order from left to right.

To simplify

Since

Next we need to evaluate the exponents. Since

The next operation we must evaluate is then the multiplication. Since

The remaining operation to evaluate is the subtraction. Subtract 32 and 8 and then subtract 100 from this result:

I am stuck here on this problem, it should be in the six stepts of quadratic equations.

$a{x}^{2}-2x-13=0\phantom{\rule{0ex}{0ex}}{x}^{2}+2x=13\phantom{\rule{0ex}{0ex}}4{x}^{2}+8x=52\phantom{\rule{0ex}{0ex}}4{x}^{2}+8x+4=52+4\phantom{\rule{0ex}{0ex}}4{x}^{2}+8x+4=56$

$a{x}^{2}-2x-13=0\phantom{\rule{0ex}{0ex}}{x}^{2}+2x=13\phantom{\rule{0ex}{0ex}}4{x}^{2}+8x=52\phantom{\rule{0ex}{0ex}}4{x}^{2}+8x+4=52+4\phantom{\rule{0ex}{0ex}}4{x}^{2}+8x+4=56$

Monotonicity of a fraction.

So I want to prove that the following fraction is monotone increasing, as a part of another proof, that's why I stumbled on:

$\frac{{4}^{n+1}}{2\sqrt{n+1}}\ge \frac{{4}^{n}}{2\sqrt{n}}$

I know it's basic, though how to prove it?
