Question

[17 x ( 25 - 8 x 3) x 1^2021 - 15] x 2^3 - 2^2 x 3

Answer 1

[17 x ( 25 - 8 x 3) x 1^2021 - 15] x 2^3 - 2^2 x 3 =
=[17 x ( 25 - 24) x 1- 15] x 8 - 4 x 3 =
=[17 x 1 - 15] x 8 - 12 =
=(17 - 15) x 8 - 12 =
=2 x 8 - 12 =
=16-12=4

Answer 2

[17 x (25-8x3)x1^2021 -15] x 2^3 -2^2 x3.
Efectuam paranteza rotunda :
25 - 8x3=25-24 =1
Inlocuim :
(17 x 1 x 1^2021 - 15 ) x 2^3 - 2^2 x 3 .
Efectuam paranteza rotunda :
17 x 1 x 1^2021 -15=17 x 1 -15 =17-15=2
Inlocuim : 2 x 2^3 -2^2 x3.
2 x 2^3 - 2^2 × 3 = 2 x 8 - 4 x 3=16 -12 =4.
Rezultatul este 4.
