Create a conversion factor from "<span>There are 6.02 × 10^23 atoms in 1 gram of hydrogen:"

6.02*10^23 atoms
-------------------------
1 gram

Then mult. 800 grams by this conversion factor:

</span>6.02*10^23 atoms 800 grams
------------------------- * ----------------
1 gram 1

This comes out to 4816*10^23 atoms, which, in scientific notation, is

4.816*10^26 atoms.

Use the quadratic formula to find the solutions to the quadratic equation below x^2-6x-5=0

Answer:

$\large\boxed{x=3-\sqrt{14}\ \vee\ x=3+\sqrt{14}}$

Step-by-step explanation:

$x^2-6x-5=0\qquad\text{add 5 to both sides}\\\\x^2-6x=5\\\\x^2-2(x)(3)=5\qquad\text{add}\ 3^2\ \text{to both sides}\\\\x^2-2(x)(3)+3^2=5+3^2\qquad\text{use}\ (a-b)^2=a^2-2ab+b^2\\\\(x-3)^2=5+9\\\\(x-3)^2=14\to x-3=\pm\sqrt{14}\qquad\text{add 3 to both sides}\\\\x=3-\sqrt{14}\ \vee\ x=3+\sqrt{14}$
