8697-[3^7:3^5+2(13-3) ]
=8697 - [3^2 + 2× 10]
=8697 - [9 +20]
=8697 - 29
=8668
8697 - \(\left[3^7:3^5+2\left(13-3\right)\right]\)
= 8697 - \(\left[3^2+2.10\right]\)
=8697 - \(\left[9+20\right]\)
= 8697 - 29
= 8668

\(8697-\) [ \(3^7:3^5+2\left(13-3\right)\) ]
= \(8697-\) [ \(3^7:3^5+2.10\) ]
= \(8697-\) [ \(3^2+20\) ]
= \(8697-\) [ \(9+20\) ]
= \(8697-29\)
= \(8668\)
\(8697-\left[3^7:3^5+2.\left(13-3\right)\right]\)
\(=8697-\left[3^2+2.10\right]\)
\(=8697-\left[9+20\right]\)
\(=8697-29\)
\(=8668\)
