Question

cuanto es -(-2)3-(-2)2-(-2)5-(-2)4​

Answer 1

Hola!

-(-2)3-(-2)2-(-2)5-(-2)4

=(2)(3)−(−2)(2)−(−2)(5)−(−2)(4)

=6−(−2)(2)−(−2)(5)−(−2)(4)

=6−(−4)−(−2)(5)−(−2)(4)

=10−(−2)(5)−(−2)(4)

=10−(−10)−(−2)(4)

=20−(−2)(4)

=20−(−8)

=28

si son potencias:

=−(−8)−(−2)^2−(−2)^5−−2(44?^4)

=8−(−2)^2−(−2)^5−−2(4^4)

=8−4−(−2)^5−−2(4^4)

=4−(−2)^5−−2(4^4)

=4−(−32)−−2(4^4)

=36−−2(4^4)

=36−(−2)(256)

=36−(−512)

=548
