Question
Answer
$$sqrt\cdot64+sqrt-9-sqrt\cdot36-sqrt-4=28qrst-13$$
Explanation
| $$ \begin{aligned}sqrt\cdot64+sqrt-9-sqrt\cdot36-sqrt-4& \xlongequal{ }64qrst+ \cancel{qrst}-9-36qrst -\cancel{qrst}-4 \xlongequal{ } \\[1 em] & \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle1}{\textcircled {1}} } }}}28qrst-13\end{aligned} $$ | |
| ① | Combine like terms: $$ \color{blue}{64qrst} + \, \color{red}{ \cancel{qrst}} \, \color{orange}{-9} \color{blue}{-36qrst} \, \color{blue}{ -\cancel{qrst}} \, \color{orange}{-4} = \color{blue}{28qrst} \color{orange}{-13} $$ |
