(3)³ +5 (3²)² -5(3)² - 7(3) - 1=

=27+5(3^2)2−5(3^2)−(7)(3)−1

=27+5(9^2)−5(3^2)−(7)(3)−1

=27+(5)(81)−5(3^2)−(7)(3)−1

=27+405−5(3^2)−(7)(3)−1

=432−5(3^2)−(7)(3)−1

=432−(5)(9)−(7)(3)−1

=432−45−(7)(3)−1

=387−(7)(3)−1

=387−21−1

=366−1

=365 → Respuesta.

Answer 2

Explicación paso a paso:

(3)³ = 27

(3²)²= 3²x²= 3⁴=81

(3)²=9

sustituimos y queda:

27+5(81)-5(9) - 7(3) - 1

Multiplicamos paréntesis

27+ 405 - 45 - 21 -1=

sumamos y quedan

365
