Question

VĂ ROG DAU COROANA !!!!!!!

Answer 1

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

Sper ca te am ajutat!
