Question
Answer
$$sqrt\cdot9-sqrt-100-sqrt\cdot36+sqrt-9=-27qrst-109$$
Explanation
| $$ \begin{aligned}sqrt\cdot9-sqrt-100-sqrt\cdot36+sqrt-9& \xlongequal{ }9qrst -\cancel{qrst}-100-36qrst+ \cancel{qrst}-9 \xlongequal{ } \\[1 em] & \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle1}{\textcircled {1}} } }}}-27qrst-109\end{aligned} $$ | |
| ① | Combine like terms: $$ \color{blue}{9qrst} \, \color{red}{ -\cancel{qrst}} \, \color{orange}{-100} \color{blue}{-36qrst} + \, \color{blue}{ \cancel{qrst}} \, \color{orange}{-9} = \color{blue}{-27qrst} \color{orange}{-109} $$ |
