Question

GT ME AJUDA PFVV, é p amanhã!!!!

Answer 1

A) $3^{x}$=243 = x=5

B) $2^{x}$=256 = x=8

C) $1000^{x}$=1 = x=0

D) $10^{x} = 1000$ = x=3

E) $5^{7x-4}=125$ = x=1

F) $2^{2x-1}=2^{4x+8}$ = x= $-\frac{9}{2}$

G) $2^{x-1}=4^{2x+4}$ = x=-3

H) $(2^{x})^3 = 8^{6-2x}$ = x=2

I) $5^{x-1} = \frac{1}{625}$ = x=-3

J) $(3^{x})^8=\frac{1}{81}$ = x=$-\frac{1}{81}$

K) $2^{x} + 2^{x+3}=18$ = x=1

L) $3^{x+5} -3^x^+^3=216$ = x=0

M) $2^{\frac{48}{x} } =8$ = x=16

N) $(\frac{1}{2})^x=32$ = x=-5

O) $2^{x-3}+2^{x-1}+2^{x} =52$ = x=5

Espero que esteja certo ^^
