Question

ajutatima va rog frumos mi trebuie urgent

Answer 1

[tex]\log_2x=4\Rightarrow x=2^4 \Rightarrow x=16 \\\;\\ b)\ \log_{\frac{1}{3}}x=0 \Rightarrow x= \left(\dfrac{1}{3}\right)^0 \Rightarrow x=1 \\\;\\ e) \ \log_{\sqrt{3}}x=-2\Rightarrow x=(\sqrt3)^{-2}=\dfrac{1}{(\sqrt3)^2}=\dfrac{1}{3}[/tex]

.

Answer 2

formula: log in baza a din A = x .... a^x=A
a) 2^4=x... x=16
b)1/3^0=x…x= 1
c)100^1=x … x= 100
d)0,3^-1=x … x=3/10^-1 … x = 10/3
e)√3^-2=x …x= 1/3
f) -8^3=x … x= -512
