Answer 1

Explicație pas cu pas:

1.a)=8+2=

=10

b)=15+3=

=18

c)=7×(12-8)=

=7×4=

=28

d)=1+2×(8-2)=

=1+2×6=

=1+12=

=13

e)=1+121÷(13-2)=

=1+121÷11=

=1+11=

=12

f)=(1+2+3+4+5+6)×21=

=21×21=

=441

2.a)x=17-3

x=14

b)x=15+23

x=38

c)x=102-15

x=87

d)3x=37+5

3x=42

x=42÷3

x=14

e)x=1751÷103

x=17

f)x=58×19

x=1102

3.a)=8

b)=9

c)=1+4+27=

=32

d)=8×4=

=32

e)=8÷4=

=2

f)=7¹⁵÷7¹⁰=

=7⁵=

=16807

4.a)2⁷²=4³⁶

4³⁶<4³⁷ ==>

2⁷²<4³⁷

b)10¹⁰⁰=(10¹⁰)¹⁰

100¹⁰=(10¹⁰)¹⁰

(10¹⁰)¹⁰=(10¹⁰)¹⁰ ==>

10¹⁰⁰=100¹⁰

c)9⁴⁰=81²⁰

81²⁰=81²⁰ ==>

9⁴⁰=81²⁰

d)2⁴⁵=(2³)¹⁵=

=8¹⁵

3³⁰=(3²)¹⁵=

=9¹⁵

8¹⁵<9¹⁵ ==>

2⁴⁵<9¹⁵

e)2¹²⁰=(2³)⁴⁰=

=8⁴⁰

3⁸⁰=(3²)⁴⁰=

=9⁴⁰

8⁴⁰<9⁴⁰ ==>

2¹²⁰<3⁸⁰

f)32²⁰=(2⁵)²⁰=

=2¹⁰⁰

16²⁵=(2⁴)²⁵=

=2¹⁰⁰

2¹⁰⁰=2¹⁰⁰ ==>

32²⁰=16²⁵
