Explicație pas cu pas:
1.
a) 3⁵= 243
9⁴= 3⁸= 6 561
429¹= 429
b) 0²⁰¹⁴= 0
123²= 15 129
10⁵= 100 000
54 321⁰= 1
c) 6⁴= 1 296
100³= 1 000 000
1005²= 1 010 025
476 259¹= 476 259
2.
a= 15²×5³:3²
a= 225×125:9
a= 3 125= 5⁵
b= 2¹⁷:8⁵×4²:32
b= 2¹⁷:2¹⁵×2⁴:2⁵
b= 2²×2⁴:2⁵
b= 2
c= 27³×9⁴:81⁴
c= 3⁹×3⁸:3¹⁶
c= 3
3.
a= (15²-8²-9²):2³-2³
a= (225-64-81):8-8
a= 80:8-8
a= 10-8= 2
b= (6³-9²-3⁴-3²):3²
b= (216-81-81-9):9
b= 45:9= 5
a la puterea b= 2⁵= 32
b la puterea a= 5²= 25
4.
a) [4³-2²×(3³-5²)]:2³
[64-4×(27-25)]:8
(64-8):8
56:8= 7
b) [(3³-5²)×4²-(15²-6³)×3]³:5³=
[2×16-(225-216)×3]³:125=
(2×16-9×3)³:125=
(32-27)³:125=
5³:125=
125:125= 1
