b) 2x = 2
c) 3x=27
d) 5× = 125
e) 6 ×= 36
l) q×= 36
9) 2× = 12
h 10× = 100ooooooo​

Answer 1

Resposta:

Explicação passo-a-passo:

a) 8x = 16

8x/2 = 16/2

x = 8

b) 2x = 2

2x/2 = 2/2

x = 1

c) 3x = 27

3x/3 = 27/3

x = 9

d) 5x = 125

5x/5 = 125/5

x = 25

e) 6x = 36

6x/6 = 36x

x = 6

l) não entendi..

g) 2x= 12

2x/2 = 12/2

x= 6

h) 10x = 100

10x/10 = 100/10

x= 10

ou

10x = 100000000

10x/10 = 10000000/10

x= 10000000
