Question

Me ajude !!!

determine a soluçao de cada equaçao exponencial a seguir :

a) 128x=1024
b)3.8x=1536
c)2x+3+2x+4=192
d)9x+5.3x+1-216=0
e)64x=1024
f)3.4x=1536
g)2x+3+2x+4=96
h)4x+5.x+1-56=0

Answer 1

a) 128x=1024

x=1024/128

x=8

b)3.8x=1536

24x=1536

x=1536/24

x=64


c)2x+3+2x+4=192

4x+6=192

4x=192-6

4x=186

x=186/4

x=93/2



d)9x+5.3x+1-216=0


e)64x=1024

x=1024/64

.x=16


f)3.4x=1536

12x=1536

x=126


g)2x+3+2x+4=96

4x+7=96

4x=96-7

4x=89

x=89/4


h)4x+5.x+1-56=0

4x+5x=55

9x=55

x=55/9

espero ter ajudado!

bom dia!
