Question

resolva as equaçoes exponenciais
8^x+1=1024

16^x+5=1\512

3^4x-7=1\2187

100000^3x+2=1\1000

3.25^x=1875

Answer 1

8^x+1=1024
2^3(x+1)=2^10
Eliminando as bases 2 temos:
3(x+1)=10
3x+3=10
3x=10-3
3x=7
x=7/3

16^x+5=1/512
2^4(x+5)=2^9*(-1)
Novamente, eliminando as bases 2, temos:
4(x+5)=-9
4x+20=-9
4x=-9-20
4x=-29
x=-29/4
