Question

resolva as equaçoes exponenciais


a)16^x+2=32^x


b)8^x+12=8^3


c)12^x=144


d)2^4x=1/8


e)5^x=^6 raiz de 25

Answer 1

Explicação passo-a-passo:

a) 2^4(x+2)= 2^5x

4x +8=5x

8= 5x -4x

x= 8

b) x+12=3

x= 3-12

x= -9

c) 12^x= 12²

x= 2

d) 2^4x = 1/2³

2^4x=2-³

4x = -3

x= -3/4

e)5^ x=6√25

5^x = 6√5²

5^x= 5^2/6

x= 2/6

x= 1/3
