Answer
$$-sqrt\cdot4+sqrt-72+sqrt\cdot64-sqrt-98=60qrst-170$$
Explanation
| $$ \begin{aligned}-sqrt\cdot4+sqrt-72+sqrt\cdot64-sqrt-98& \xlongequal{ }-4qrst+ \cancel{qrst}-72+64qrst -\cancel{qrst}-98 \xlongequal{ } \\[1 em] & \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle1}{\textcircled {1}} } }}}60qrst-170\end{aligned} $$ | |
| ① | Combine like terms: $$ \color{blue}{-4qrst} + \, \color{red}{ \cancel{qrst}} \, \color{orange}{-72} + \color{blue}{64qrst} \, \color{blue}{ -\cancel{qrst}} \, \color{orange}{-98} = \color{blue}{60qrst} \color{orange}{-170} $$ |
