Hey...I'm picking on you!
But the other three were correct
Well then.....LOL.... I thought it was kind of funny.
It might have been
I know that was the point I thought it was funny.
$${\mathtt{a}} = {\frac{\left(\left({{\mathtt{8}}}^{-{\mathtt{2}}}\right){\mathtt{\,\times\,}}{{\mathtt{2}}}^{{\mathtt{7}}}\right)}{{{\mathtt{2}}}^{{\mathtt{6}}}}} \Rightarrow {\mathtt{a}} = {\mathtt{0.031\: \!25}}$$
$${\mathtt{4\,012}}{\mathtt{\,\small\textbf+\,}}{\mathtt{3}}{\mathtt{\,\times\,}}{\mathtt{3}}{\mathtt{\,-\,}}{\mathtt{3}} = {\mathtt{4\,018}}$$
whoa wait, ((8^-2)*2^7)/2^6
$${\mathtt{\,-\,}}{\mathtt{3}}{n}{\mathtt{\,\small\textbf+\,}}{\mathtt{\,\small\textbf+\,}}{\mathtt{18}} = {\mathtt{\,-\,}}{\mathtt{3}}{n}{\mathtt{\,\small\textbf+\,}}{\mathtt{18}}{\mathtt{\,\small\textbf+\,}}$$
You said ketchup not catch up
So sorry I meant 8^-2x2^7, not 8^-2.2^7
LOL I know.
$${\mathtt{a}} = {{\mathtt{8}}}^{{\mathtt{\,-\,}}\left({{\mathtt{2.2}}}^{{\mathtt{7}}}\right)} \Rightarrow {\mathtt{a}} = {\mathtt{0}}$$
$${\mathtt{b}} = {{\mathtt{4}}}^{-{\mathtt{3}}} \Rightarrow {\mathtt{b}} = {\mathtt{0.015\: \!625}}$$
Hit log then type 1/2 then (9) then enter
$${\frac{{\mathtt{log1}}}{{\mathtt{2}}}}{\mathtt{\,\times\,}}\left({\mathtt{9}}\right) = {\frac{{log}_{10}\left({\mathtt{1}}\right)}{{\mathtt{2}}}}{\mathtt{\,\times\,}}{\mathtt{9}}$$
$${\mathtt{Sinx}}{\mathtt{\,\small\textbf+\,}}{{\mathtt{sinxcot}}}^{{\mathtt{2}}}{\mathtt{\,\times\,}}{\mathtt{x}} = {\mathtt{cscx}} \Rightarrow {\mathtt{sinx}} = {\mathtt{cscx}}{\mathtt{\,-\,}}{{\mathtt{sinxcot}}}^{{\mathtt{2}}}{\mathtt{\,\times\,}}{\mathtt{x}}$$
Ketchup is a dipping sauce made of tomatoes!
