Explicație pas cu pas:

1)

a)

=1²/3²

= 1/9

b)

= (-7/5)²

=( 7/5)²

= 7²/5²

= 49/25

-

c)

= (-3/2)³

= -3³/2³

= -27/8

-

d)

= (-5/10)⁴

= 5⁴/10⁴

= 625/ 10.000

= 0,0625

e)

= (-3/9)³

=(-1/3)³

= -1³/3³

= - 1/27

-

f)

= (-7/6)²

= (7/6)²

= 7²/6²

= 49/36

-

2)

a)

=2⁻³

= 1/2³

= 1/8

-

b)

= 1⁴/(-2)⁴

= 1/2⁴

=1/16

-

c)

= (9)⁻¹

= 1/9¹

= 1/9

-

d)

=( 1/2²)⁻¹

= (1/4)⁻¹

= 1/1/4

= 1*4/1

= 4

-

e)

= (2/1)⁵

= 2⁵/1⁵

= 32/1

=32

-

f)

=[(-3/2)⁻²]²

= (-3/2)⁻⁴

= ( -2/3)⁴

= 2⁴/3⁴

= 16/81

-

g)

=[(1/4)⁻¹]²

= (1/4)⁻²

= (4/1)²

= 4²/1²

= 16/1

= 16

-

3)

a)

(1/3)¹⁵<(1/3)²⁵

-

b)

(7/2)⁵< (7/2)¹⁰

c)

=(3/2)⁴ >(-3/2)¹¹
