EQUAÇÃO EXPOTENCIAL

1) 5^x1/5

2) 3^x=9

3) 4^x=64

4) 10^x=100

5) 6^x=216

Answer 1

$5^x= \dfrac{1}{5}\Rightarrow5^x= \dfrac{1}{5^1}\Rightarrow\not5^x=\not5^{-1}\Rightarrow \boxed{x=-1}\\\\ 3^x=9\Rightarrow\not3^x=\not3^2\Rightarrow \boxed{x=2}\\\\ 4^x=64\Rightarrow\not 4^x=\not4^3 \Rightarrow \boxed{x=3}\\\\ 10^x=100\Rightarrow \not10^x=\not10^2 \Rightarrow \boxed{x=2}\\\\ 6^x=216\Rightarrow\not 6^x=\not6^3\Rightarrow \boxed{x=3}$
