Question

A) 2 – [+ 3 + 4 · (6 – 8)] : (– 5)b) [– 4 la 2 + (– 5) · (– 3)]la 10 + [(– 3)la 3+ (– 2) · (– 14)] la 11

Answer 1

Răspuns:

Explicație pas cu pas:

a) 2-[3+4(6-8)]:(-5)=

=2-[3+4*(-2)]:(-5)

=2-(3-8):(-5)

=2-(-5):(-5)

=2-1

=1

b) $[-4^2+(-5)(-3)]^{10}$+$[(-3)^3+(-2)(-14)]^{11}$=

=$(-16+15)^{10}$+$(-27+28)^{11}$

=$(-1)^{10}$+$(-1)^{11}$

=1-1

=0
