Question

$- 9 {}^{2} + (3 {}^{2} ) {}^{2} + ((1 {}^{ - 5}) {}^{ - 1} \times ( - 4) {}^{2} )$
alguien sabe resolverlo?​

Answer 1

(−9)(2)+(3)(2)(2)+1−5−(1)(−4)(2)

=−18+(3)(2)(2)+1−5−(1)(−4)(2)

=−18+(6)(2)+1−5−(1)(−4)(2)

=−18+12+1−5−(1)(−4)(2)

=−6+1−5−(1)(−4)(2)

=−6+−4−(1)(−4)(2)

=−6−4−(−4)(2)

=−6−4−(−8)

=−6+4

=−2

espero que te sirva suerte!!!!
