Answer 1

Răspuns:

a) (49 - $5^{2}$) · (49 - $6^{2}$) · (49 - $7^{2}$) · (49 - $8^{2}$ ) = 0

1) 49 - $5^{2}$ =  24

2) 49 - $6^{2}$ = 13

3)  49 - $7^{2}$ = 0

4) 49 - $8^{2}$ = -15

5) 24 · 13  = 312

6) 312 · 0 = 0

7) 0 · (-15) = 0

c)$(-2)^{3}$ + 10 ·  $[(-1)^{2018}$ + $(-1)^{2019}$ + 2 · (2 · 3 - 2)] = 72

1) 2 · 3 - 2 = 4

2)  $(-1)^{2018}$ = 1

3) $(-1)^{2019}$ = -1

4) 2 · 4 = 8

5) 1 + (-1) = 0

6) 0 + 8 = 8

7) $(-2)^{3}$ = -8

8) 10 · 8 = 80

9) -8 + 80 = 72

d) $(-3)^{199} : (-3)^{198} - 4$ · { -2 -2 · [$(-4)^{8}$ : $2^{14}$ -2 ]} = 21

Eu nu sunt sigura ca e corect!

Sper ca te-am ajutat!
