Solving radical equation
Darya [45]
\bf \sqrt{k-9}-\sqrt{k}=-1\implies \sqrt{k-9}=\sqrt{k}-1\impliedby \textit{squaring both sides}
\\\\\\
(\sqrt{k-9})^2=(\sqrt{k}-1)^2\implies k-9=(\sqrt{k}-1)(\sqrt{k}-1)\impliedby \textit{FOIL}
\\\\\\
k-9=k-2\sqrt{k}+1\implies -10=-2\sqrt{k}\implies \cfrac{-10}{-2}=\sqrt{k}
\\\\\\
\sqrt{\cfrac{-10}{-2}}=k

Use the function below to find F(2)
ki77a [65]

Using the function 2*1/2^3t given, it is just to input the value given to the function.
Or in other words, replace the letter, with the number.
Like this 
F(2) = 2*1/2^3*2
F(2) = 2*1/2^6
F(2) = 2*1/64
F(2) = 2/64 = 1/32

1/32 is the answer.
If your formatting was correct. :)
