Question

Resolva a equação exponencial : a) (1/7)^3x-6= 1

Answer 1

Ola Maestro

(1/7)^(3x - 6) = 1 

(1/7)^(3x - 6) = (1/7)^0 

3x - 6 = 0
3x = 6
x = 6/3

x = 2

Answer 2

(1/7)^3x-6= 1 $\frac{1}{7} ^{3x-6}=1 \\\\ \frac{1}{7} ^{3x-6}=\frac{1}{7}^0 \\\\3x-6=0 \\ \\3x=6 \\ \\x= \frac{6}{3} \\ \\x=2$
