Answer 1

Explicație pas cu pas:

1

Simplif  {0}^{2002}02002  la  00.

{2023}^{0+{1}^{2018-0}}+{3}^{1}20230+12018−0+31

2

 Simplificam 2018-02018−0  la  20182018.

{2023}^{0+{1}^{2018}}+{3}^{1}20230+12018+31

3

Simplificam  {1}^{2018}12018  la  11.

{2023}^{0+1}+{3}^{1}20230+1+31

4

Simplificam  0+10+1  la 11.

{2023}^{1}+{3}^{1}20231+31

5

folosim regula de 1: {x}^{1}=xx1=x.

2023+{3}^{1}2023+31

6

folosim regula de 1  {x}^{1}=xx1=x.

2023+32023+3

7

Simplificam 2026

b)Simplif  {3}^{2}32  to  99.

9+2\ori 5-72\div 99+2×5−72÷9

2

Simplif  2\ori52×5  la  1010.

9+10-72\div 99+10−72÷9

3

Simplif 72\div 972÷9  la  88.

9+10-89+10−8

4

Simplif  9+109+10  la  1919.

19-819−8
