Question

equacao exponencial alguem pode me ajudar??? :(raiz quadrada de 1/2)^X=1/128 ALGUEM ME AJUDA ??????

Answer 1

$\left( \sqrt{\dfrac{1}{2}}\right)^x= \dfrac{1}{128} \\ \\ \\ \left[\left(\dfrac{1}{2}\right)^{ \frac{1}{2} }\right]^x= \left(\dfrac{1}{2}\right)^7 \\ \\ \\ \left(\dfrac{1}{2}\right)^{ \frac{x}{2} }= \left(\dfrac{1}{2} \right)^7$

Bases iguais, expoentes iguais:

$\dfrac{x}{2} =7 \\ \\ x=7\cdot2 \\ \\ \boxed{x=14}$
