Va rog repede ex 13 repede va rig din suflet fac orice dau coroana dau inimi dau steluțe orice va rog din suflet dau 25 de puncte va rog

Answer 1

Explicație pas cu pas:

a) 4⁷= (2²)⁷= 2¹⁴

2¹⁴:2¹⁰= 2⁴

b) 4¹⁰= (2²)¹⁰= 2²⁰

8⁷= (2³)⁷= 2²¹

2¹⁵×2²⁰×2²¹= 2⁵⁶

c) 9¹⁵= (3²)¹⁵= 3³⁰

3³⁰×3⁷= 3³⁷

d) 4²³= (2²)²³= 2⁴⁶

2⁵¹:2⁴⁶= 2⁵

e) 8⁷= (2³)⁷= 2²¹

4¹⁰= (2²)¹⁰= 2²⁰

2²¹:2²⁰×2¹⁷=

2¹×2¹⁷= 2¹⁸

f) 27¹⁰= (3³)¹⁰= 3³⁰

9²⁰= (3²)²⁰= 3⁴⁰

3³⁰×3¹⁵:3⁴⁰=

3⁴⁵:3⁴⁰= 3⁵

h) 12= 2²×3 => 12⁷= 2¹⁴×3⁷

(2¹⁴×3⁷) : (2¹⁰×3⁵)=

2⁴×3²= 144

i)

(2¹⁴×3²⁰)²:(2²⁵×3³⁹)=

(2²⁸×3⁴⁰):(2²⁵×3³⁹)=

2³×3= 24

$j)( {4}^{n} \times {3}^{2n + 1} ) \div ( {2}^{2n} \times {9}^{n) =}$

$( {2}^{2n} \times {3}^{2n} \times {3}^{1} ) \div ( {2}^{2n} \times {3}^{2n} )$

= 3
