Explicație pas cu pas:

5³:[2⁵-(7×2⁷:14-7⁰):3²] =

125:[32-(7×128:14-1):9] =

125:[32-(896:14-1):9] =

125:[32-(64-1):9] =

125:(32-63:9) =

125:(32-7) =

125:25 =

5

[11²+(9²-5×7³:35):2³]:5² =

[121+(81-5×343:35):8]:25 =

[121+(81-1715:35):8]:25 =

[121+(81-49):8]:25 =

(121+32:8):25 =

(121+4):25 =

125:25 =

5
