Question

resolva as equações exponenciais
100000000=10x
12 2x=1

Answer 1

100000000=10x
    10^7 = 10^x
        x = 7

12^2x = 1
 12^2x = 12^0
     2x= 0
       x= 0

Answer 2

100000000 = 10^x
10^8 = 10^x
elimine as bases (10)
x = 8

12^2x = 1
12^2x = 12^0
elimine as bases(12)
2x= 0
x= 0/2
x = 0
